New description: [New technical field] The present invention relates to a wide-angle mirror for an automatic teller machine, in particular to a color photographic imaging device M350037 which can penetrate a plated dielectric film wide-angle mirror. Technology] At present, financial institutions are mostly located inside or outside bank buildings, or in convenient metropolitan areas, and there are ATMs to facilitate the withdrawal of cash services from the public. 〇Because the services of ATMs are often required The action of the person typing the password. When the cashier types the password, the ATM will often set a small wide-angle reflection in order to avoid the other people who are queued behind or around the cashier to see the password typed by the cashier. The mirror (micro-convex mirror, non-planar mirror) is placed at the appropriate position on the cash dispenser to allow the cashier who is typing the data to face the reflected image of the small-angle mirror to monitor other people behind or around. . In some metropolitan areas where security is not good, it is also common for the cashier to complete the password when it is being withdrawn. Therefore, in addition to the small-sized wide-angle mirrors, some cash dispensers are equipped with a camera for monitoring and simultaneous video recording. In fact, in some respects, the "obvious" surveillance camera can achieve a level of deterrence against the smugglers of the sneak peek and robbery. M350037 C is 'in some ways the device is "obvious" $ Surveillance cameras sometimes cause uncomfortable dislike of the level of the cashier. If the cashier knows: (4) Tibetan surveillance cameras, and their surveillance cameras* are (four) obvious: There is not such an uncomfortable dislike in shooting pre-paid money. Moreover, if a wide-angle mirror and a surveillance camera are simultaneously placed in the proper position on the front of some cash dispensers, the automatic withdrawal opportunity creates a certain degree of difficulty in construction and maintenance. In addition, the "Aluminum Dome Cover Camera Device" of the Republic of China, No. 326646, which was obtained by myself, is equipped with a surveillance camera behind an awning hemispherical mask, using an aluminized hemispherical mask. The transmitted visible light causes the surveillance camera to image. However, the mirror effect of the key aluminum hemispherical mask was found to be slightly awkward. • Aluminium (Al) is a type of metallized reflective film. The general metal reflective film has the advantages that the preparation process is simple, and the working wavelength range is large, and the reflection band is relatively wide; the disadvantage is that the optical loss is large, the reflectance is not high, and the reflectance is increased, and the visible light reflection can achieve a better mirror effect. However, it does reduce the visible light transmittance and directly affect the image quality. 7 M350037 [New Content] The problems to be solved in this creation are: How to set up a color camera for monitoring in a small wide-angle mirror on an automatic teller machine? And how can I increase the reflectivity and penetration of small wide-angle mirror lenses? The technical solution adopted by this creation is: Replace the metallized (for example, plated) film wide-angle mirror lens with a plated dielectric film wide-angle mirror lens. As in the metallized film wide-angle mirror disclosed in the prior art, the optical loss of visible light is large, the reflectance is unlikely to be high, and the reflectance is not high, and the mirror effect is poor. Therefore, it is a feasible technical solution to reduce the optical loss of visible light, increase the reflectivity to form a mirror effect and increase the transmittance to increase the imaging effect, and to replace the metallized film with a dielectric film. A brief discussion of the relationship between the incident light and the coated wide-angle mirror is as follows: Assuming that the incident light is L, the reflected light of the coated wide-angle mirror is R, the transmitted light of the coated wide-angle mirror is τ, and the absorbed light of the coated wide-angle mirror is A. . M350037 The incident light L is equal to the reflected light R of the wide-angle mirror of the film plus the transmitted light T of the coated wide-angle mirror plus the absorbed light a of the forged wide-angle mirror. Its simple mathematical relationship is l=r+t+a. If the absorbed light A of the coated wide-angle mirror is small or negligible to zero, then L = R + T, that is, 'under a certain incident light L, the transmitted light T of the forged film wide-angle mirror and the wide-angle reflection of the coating The reflected light R of the mirror is inversely proportional. ^ The more incident light L is incident on the coated wide-angle mirror, the less light is reflected. Conversely, the less incident light L passes through the coated wide-angle mirror, the more light is reflected. To put it simply, replacing a metallized film wide-angle mirror with a plated dielectric film wide-angle mirror means that the dielectric film absorbs light less than the metal film absorbs light. If the transmitted light is constant, the plated dielectric film wide-angle reflector reflects more light than the metal-coated wide-angle mirror. Reflected light More mirrors are more beautiful. Similarly, if the reflected light is constant, the penetrating light of the plated dielectric film wide-angle mirror is more than that of the metal-coated wide-angle mirror. More penetrating light is better for color cameras. Therefore, the plated dielectric film wide-angle mirror has more advantages than the metal-coated wide-angle mirror. 9 M350037 Plating Dielectric Film Wide-angle mirrors are formed by coating dielectric coatings on a transparent substrate. The transparent substrate is a transparent glass sheet or a partially optical grade transparent resin (such as PC, Polycarbonate polycarbonate resin, PMMA, acrylic) which has been cleaned and has a smooth surface (the surface is rough if it is scattered to the incident light). A material of a dielectric film is a material that is transparent to visible light. For example, conventional titanium oxide (Ti〇2, refractive index of 2.2) and cerium oxide (Si〇2, refractive index of 1.54) can be used. The two kinds of high and low refractive index coating materials are alternately evaporated on the transparent substrate, and after completion of the cleaning process, a plated dielectric film wide-angle mirror is completed. In addition to the above titanium dioxide and oxidizing hair, the film material is also selected, for example, pentoxide pentoxide Ta2 〇 5 is also a high refractive index material, and is transparent from visible light to infrared. For example, Nb2〇s is also a high refractive index material between Ti〇2 and Taws. Fluoride is generally a low refractive index material. The [transparent] on the transparent substrate in the plated dielectric film wide-angle mirror mainly means colorless transparency. It mainly allows the visible light to pass smoothly. If the red 10 M350037 color transparent substrate is used, the visible light passes through (most of the red light passes through), which has a so-called red color shift phenomenon, which affects the image quality. If a red (or other color) opaque substrate is used, visible light cannot pass and cannot be imaged. The plated dielectric film wide-angle mirror utilizes the interference effect of the film and the film layer design to cause the wide-area incident light to be properly split into two optical paths. The incident light is incident on the plated dielectric film wide-angle mirror interface. One part penetrates the plated dielectric film wide-angle mirror interface, and the other part reflects from the plated dielectric film wide-angle mirror interface. The larger the incident light penetrating the plated dielectric film wide-angle mirror interface, the better the image quality. The greater the light reflected from the plated dielectric film wide-angle mirror interface, the better the mirror effect. When the background of the plated dielectric film wide-angle mirror is dark or black, in the general environment (for example, an illumination environment of about 2 〇〇 Lux), the human eye is observed from the front side of the plated dielectric film wide-angle mirror, When the reflected light is more than 5〇%, the effect of the mirror surface is not exhibited. More than 60% of the reflected light is like a mirror. When the reflected light is close to 7〇%, the plated dielectric film wide-angle mirror is like a mirror. M350037 In the mathematical method L=R+T+A briefly discussed above, in the general illumination environment, it is assumed that: the illumination of the incident light L is 200 Lux, the reflected light of the coated wide-angle mirror is 80%, and the wide-angle reflector of the film The transmitted light T is 20%, and the absorbed light A of the coated wide-angle mirror is 0% (in fact, it is not 〇%, only the imaging effect on the device is small, compared with the absorption of light by the metal film, Small enough to ignore.) When the transmitted light T is 20% through the coated wide-angle mirror to the color camera behind it, the color camera lens has a light input of about 40 Lux (200 Lux multiplied by 20%). 5Lux。 The minimum illuminance (indicated by the current manufacturer's specification) that can be sensed by the image sensor of a commercially available color camera (about 0. 5 Lux). Some of the high-end type is about 〇. lLux, and there is also a product called a star-level product whose low illumination is about 0. 02Lux. The image sensor with the low-order Cmos is also about 5Lux. With the lowest-order 5Lux image sensor, the 40Lux light input is also sufficient. When the illumination of the desired environment drops to the point where the image sensor is not adequately sensed, the image with the snowflake-like spot 12 M350037 is often displayed on the monitor, resulting in poor imaging quality or failure to image. This allows you to change higher-end cameras in the desired environment or to increase the auxiliary light source required for imaging. In practical applications, if there is only one color camera on the back of the plated dielectric film wide-angle mirror, there are still two problems. · The first is how to structure a color camera on the back of a plated dielectric film wide-angle mirror. ? The second is that the front and back of the wide-angle mirror of the key dielectric film have a transmittance of 20 〇/〇. How can the plated dielectric film wide-angle mirror produce hidden decoration and image interference for the color camera? The method is to add an interface. A color camera is disposed inside the interface body by using an interface body; a plated dielectric film wide-angle mirror is disposed on one side of the interface body. Thus, the photographic lens of the color camera is aligned and adjacent to the plated dielectric film wide-angle mirror. 0 13 M350037 Using an interface body, the incident light is incident when it is incident on the plated dielectric film wide-angle mirror. The light is divided into three parts. Most of them (for example, 80%) are reflected back on the outer surface of the plated dielectric wide-angle mirror (the human eye only sees this reflected image). A small part (for example, 20%) is divided into two lights. One light enters the photographic lens of the smaller area and the other falls outside the photographic lens of the larger area. The light of another large area that falls outside the photographic lens is removed or attenuated within the interface body by absorption and scattering when it is incident on the interface body. In order to prevent the transmissive body and the plated dielectric film from being reflected by the inner surface of the wide-angle mirror, the image is superimposed into the photographic lens to cause overlapping reflection images. The function of absorption and scattering is achieved inside the interface. The simple method is to opaque the inside of the interface and to make the internal surface black to absorb the incident light (20%) of the internal surface. The inner surface of the interface body is also made into a rough surface, and the unabsorbed light is dispersed again, so that the light that can be directly entered into the camera lens is very small, and the interference is insufficient. Therefore, basically, the creation includes a plated dielectric film wide-angle mirror, a color camera, and an interface body. The technical effects of the technical solutions and features adopted by this creation: 14 M350037 One of the effects of this creation, the outer surface of the plated dielectric film wide-angle mirror of the device presents a highly reflective mirror surface, and the cashier uses a mirror surface in front of the cash machine. The reflected image can clearly see other people behind or around it to monitor whether their withdrawal actions have been peeked. The second effect of this creation is that the penetrating light of the plated dielectric film wide-angle mirror of the device can reach the imaging condition of the color camera in the mirror, so that the owner of the cash dispenser can perform video recording and monitoring at the far end. The third effect of this creation is that the plated dielectric film wide-angle mirror of the device can achieve the protection effect for the color camera in the mirror, and the color camera can reach the plated dielectric film wide-angle mirror. The effect of the extendable field of view results in a complementary multiplication effect.

As shown in FIG. 1 , the device 100 includes a plated dielectric film wide-angle mirror 10 , a color camera unit 20 , and a black circular chassis 30 . The micro-convex (non-planar) plated dielectric film wide-angle mirror 10 is cut into a circular shape, and the circular shape is approximately smaller than the black circular chassis 30. The edge of the circular chassis 30 is provided with an elastic protruding card holder 31. The plated dielectric film wide-angle mirror 10 is attached to the circular chassis 30 and then pressed by hand to insert the bell dielectric film wide-angle mirror 10 into the disk. The inside of the deck 31. Such a process is simpler to assemble than a lock screw. The black circular chassis 30 is a circular shaped chassis formed by injection molding of black plastic. The circular shaped chassis is not necessarily black, and may be other dark-colored opaque chassis, which is mainly opaque. The circular shaped chassis does not necessarily have a circular shape, and other shapes are also possible. Mainly with the shape of the plated dielectric film wide-angle mirror 10. The inner surface of the circular chassis 30 is preferably formed with a rough surface so that the human (4) county ((4)%) is scattered around the rough surface on the chassis surface after wearing the thief wide-angle mirror 10. In order to avoid re-reflecting into the photographic lens 2i of the color photography unit 20 via the chassis surface of the M350037, an image with overlapping images is formed, which affects the image quality. The circular chassis 30 is cut into a hole 32' hole 32 which is sized to fit into a color photography unit 20 casing. The color photographic unit 20 and the circular chassis 3 〇 are held by screws by a plurality of L-shaped brackets 33. The photographic lens 21 of the color photographic unit 2 faces the inner surface of the plated dielectric film wide-angle mirror 1 ,, so that the incident light L20 of the f-forged dielectric film wide-angle mirror 10 can directly enter the photographic lens of the color camera unit 20. 21 imaging. The tail end 22 of the color photographing unit 20 serves as a lead-out line for the power and image signals of the color photographing unit 20, and a waterproof rubber loop can be added to the lead-out port for waterproofing. The black circular chassis 30 has a black background as if it were a carded dielectric film wide-angle mirror. When the incident visible light L10 is incident on the outer surface of the bell-shaped dielectric film wide-angle mirror, 'L10 (100%) is divided into two paths'. The way is to reflect on the outer surface of the forged dielectric film wide-angle mirror 10, and its reflected light Lli ( 8〇〇/0) For the cashmer's human eye 10a, the plated dielectric film wide-angle mirror 1 〇 front surface is like a bright wide-angle lens, so that the cashier can clearly see himself and the surrounding 17 M350037 Reflect the image. The other way is that the transmitted light L12 (20%) is mostly absorbed by the black circular chassis 30, and the remaining unabsorbed is scattered by the circular chassis 30 - rough surface. After a small amount of astigmatism is scattered through the plated dielectric film wide-angle mirror 10, the light that can be penetrated at the end is almost zero (minimum value is ignored). This makes it almost impossible for the cashier to see the color photography unit 20 after plating the dielectric film wide-angle mirror 10. When another incident visible light L20 is incident on the surface of the plated dielectric film wide-angle mirror 10, L20C100%) is also divided into two paths, one for reflected light L21 (80%) and the other for transmitted light (20%). After the transmission of the dielectric film wide-angle mirror 10 is transmitted, the color imaging unit is further imaged. Therefore, a color camera unit 20 can be constructed on the back side of a plated dielectric film wide-angle mirror by using an interface vessel (black circular chassis) 30. And the use of an interface body 30 allows the plated dielectric film wide-angle mirror 1 to achieve a hidden decoration and protection function for the color photography unit 20. The color photography unit 20 used in this embodiment is a commonly-used CCD-like charge CCD (charge-Coup ed Devices) module (with a medium-aluminum outer casing) including a photographic lens (Lens) and a control circuit board. The control circuit board has an image sensor (丨mage Sensor) image processing control M350037 circuit. Both the CCD image sensor and the CM〇s image sensor are made of dream wafers, and the amount of money for the visible near infrared (four) is basically similar. The Miscellaneous New Art Shop is made up of a fine photoelectric conversion process that converts the image A-light iiU into f-voltage (electricity). If a color sensor is also needed, then each pixel is covered with color (R, G, B). Can be used to extinguish the film. At present, both the CCD 5 Ge and the CMos photography module can respond to the wave domain from visible light to infrared. The ccd^cmgs photography module can be defined in the 2Q definition of the color shooting group. As shown in Fig. 本, the device comprises a plated dielectric film wide-angle mirror 10, a color photography unit 2〇' and an interface body 3〇. Among them, the color shooting group 20 and the interface body 3 are all products of the conventional technology. Please refer to FIG. 2, which is a diagram of a plate module of a conventional color camera. Please refer to Figure 2A for the color crew of the device. & Figure 2' The conventional conventional color camera module (without aluminum housing) basically includes an infrared LED lamp set 22 and a circuit control board 23. Commonly known as a plate-shaped CCD camera, the infrared LED lamp group 22 is used to emit an infrared light source when the ambient illumination is insufficient. The circuit control board 23 performs processing control on the imaging. 19 M350037 Built-in general color light-receiving module with infrared LED light level 22, in order to avoid the infrared emitted by the infrared LED light group 22 because of reflection, it will cause interference. In practical applications, most of the black collar 21a is set on the lens 21. To prevent reflections from drying ":. The device (4) color township unit 2 unicorn has built-in infrared LED lamp group 22 has a black trap 2ia.囷二A is a schematic diagram of the color photography unit 20 of the device. The black snare 2ia on the photographic lens 21 can be displaced up and down in the photographic lens 21 such that one end of the black snare 21a can be immediately adjacent to the inner surface of the plated dielectric film wide-angle mirror 10 as shown in FIG. 1 for the purpose of making the photographic lens 21 The incident light is limited only to the transmitted light directly transmitted through the plated dielectric film wide-angle mirror 10 before the photographic lens 21.

Next, the detailed description of the plated dielectric film wide-angle mirror 10 will be described. . M350037 The above-mentioned plated dielectric film wide-angle reflector ίο is a transparent substrate on a β-coated dielectric film wide-angle mirror 10 formed by plating dielectric coatings on a transparent substrate (Substrate). [Transparent] mainly allows visible light to pass smoothly. The substrate can be roughly divided into glass and plastic. Glass has Soda-lime glass, German white glass (D263T), heat-resistant glass (B0R0SILICATE) and so on. Commonly used plastics are optical grade transparent resins such as PC 'Polycarbonate polycarbonate resin (88% transparency), and PMMA acrylic (93% transparency). Other resins that are transparent in industrial plastics are also available. For example: PS (transparency 89%), CR-39 (transparency 90%), SAN resin (transparency 90%), MS resin (transparency 90%, poly-4-decylpentene _ (TPX) (transparency > 90) In addition, transparency such as poly(methyl sulphate), styrene copolymer (MAS), PET, PP, and PVC is very good. [Transparent] on transparent substrates must first have high transparency and must require surface quality. Strict requirements, try not to have any defects such as streaks, pores, whitening, fog, black spots, discoloration, poor gloss, etc. The purpose of transparency and smooth surface is mainly to allow infrared to pass smoothly, avoiding or reducing scattering. The embodiment is formed by transparent optical grade PC (Polycarbonate) polycarbonate resin in a mold and then cut into a PC transparent disc having a diameter of about 1 cm and a thickness of about 2 mm (slightly convex shape to form a wide-angle mirror after coating). ), P The surface of the C transparent disc should be very smooth (the surface roughness will cause the incident light to scatter on the surface, affecting the image quality), and the PC transparent disc is cleaned and sent to the vacuum coater for coating.

射鏡10樣品一，兩者所呈現的色澤不完全一樣，但是均呈 現亮麗的鏡面反射，都好像一面真實的明鏡鏡子。 如圖三Α所示，穿透率在光譜波長740nm左右由20%上 升到約95%以上。這顯示鍍介電質膜廣角反射鏡1〇樣品二 可以透過可見光約20%而且對紅外具有很高的穿透率。 簡單說，鍍介電質膜廣角反射鏡10樣品二所搭配的彩 色攝影機組20，在有紅外的環境下可攝取到紅外影像。而鍍 介電質膜廣角反射鏡10樣品一所搭配的彩色攝影機組2〇， 在有紅外的環境下也不可或不容易攝取到紅外影像。 26 M350037 也就是說，自動提款機前環境照度不足時，鍍介電質 膜廣角反射鏡ίο樣品一的成像效果相對很差。鍍介電質膜 廣角反射鏡10樣品二則在紅外輔助光源可以看到清楚的紅 外影像。 但是在全球各地幾乎所有的自動提款機都設置在以有 足夠環境照度下，以便利提款人提款操作照明，也可以因

弧度角太大(例如像半圓形狀），穿透鍍介電質膜廣角反射 鏡10的再反射光未經過黑色圓形底盤30的吸收與散射，則 • 再透過鍍介電質膜廣角反射鏡10穿透出去的部份光，會使 提款人人眼10a隱約看到鍍介電質膜廣角反射鏡10後彩色 攝影機組20。 今曰在薄膜光學上，我們很容易由向量法或導納軌跡 法在光學級基板上鍍折射率高低交互變化的多層四分之一 波膜堆可獲得預期的穿透率T%。而且理論上也同時可以證 28 M350037 明用相同多膜層數，四分之一波膜堆比非四分之一波膜堆 所得到的反射率要高。而臈層數越多則R%反射率也越大。 也就是說，很容易控制穿透與反射的分光比例。 在目前現有可用的艘膜材料在可見光區高折射率小於等 於2.4而低折射率大於等於1.35，所以單一的四分之一波 膜堆的高反射帶的寬度是有限的。因此，要滿足本實施例在 可見光區能夠像金屬膜一樣有較寬的反射帶，有必要將全 介電質膜高反射帶拓寬。 拓寬的方法有之一，是使膜系之每層濃度有規則的遞 增（可依等比級數或等差級數），如此可使很寬的區域内 的任何波長都有足夠多的膜層，其光學濃度也足夠接近四 分之一波。不過如此作成之高反射區反射率會有許多下降的 波紋，必須用優化法再行優化之。其他的方法還有將一個中 心波長稍短之四分之一波膜堆疊加在另一個四分之一波膜 堆上。 有關鍍膜的設計基本上可從標準膜系開始著手，例如高 反射鏡不管波寬大小或單或雙波數，都一律以四分之一波 膜堆基礎來設計。 29 M350037 當初始設計無法滿足需求的光學成效時，就利用目前 商用設計的電腦軟體來優化或合成。有些優化所用的是數學 技巧而且不斷的改進中。例如最常用的有簡形優化法 (Simplex method )、最小平方調適法（Least-square fit or damped least squares)及合成法。 本實施例就是將設計好的各膜層參數數據再委托廠商 _ 以真空蒸鍍完成如圖三與圖三A光譜的鍍介電質膜廣角反射 鏡10。同樣的膜層設計在不同廠牌鍍膜機會產生不同的光譜 對於同一機台内加熱分佈溫度、膜材更換、基板形狀大小都 影響每層鍍膜的特性。在量產鍍介電質膜廣角反射鏡1〇時 以一專用的機台比較經濟。 請參閱圖四為薄膜反射率R%與光學厚度的變化關係圖。 • 由光學薄膜干涉現象可知，當光垂直（正面0度)入射 單層膜時’且光學厚度Nd (為薄膜折射率與薄膜厚度的 乘積）為（21«)/2)、又()、（34〇/2>..膜層對波長的反光強度 不變；若光學厚度Μ為（λ〇/4)、 （3又0/4)、 (5λ〇/4)…’反射率將為極大值或極小值，且其值決定於膜 的折射率η是大於還是小於基板的折射率沾當n〉nS時， 反射率為極大值，在n < nS時，反射率為極小值，如圖 M350037 六所示。由圖四可見，一層光學厚度為入射光波長四分之一 奇數倍，讓反射波形成破壞性干涉，即可得反射率為〇之減 反射效果。但對其他波長的反射率並非為〇，因而為了在可 見光範圍可得寬廣的反射率通常都是多層架構，適當選擇 膜層的折射率與膜層設計就可得到適當的反射率。由圖四可 見分析可H光料度為四分之-波長，且折射率夠 低的薄膜，可作為抗反射膜，使表面反射率降低，例如在 玻璃（BK7 ’ η = 1.53)表面鍍上單層氟化鎂（啦匕，n = 1. 38)，即為一種簡單架構的抗反射膜。相對的，若在玻璃 表面鍍上一層折射率足夠高的材料，它將大大增加玻璃表 面的反射率，因此這種薄膜可作為一種很好的分光鏡，單 層的二氧化鈦（Ti02，η = 2.2)或硫化鋅(znS，η = 2 35) 薄膜常作為這種用途，反射率約可達30%左右。 基本上單層膜的疊加就是多層膜。當使用多層薄膜時， 可以依照我們的需要，運用高低折射率薄膜堆疊，做各式 各樣的薄膜設計，以產生我們所要求的光學特性。常見的如 抗反射鏡、高反射鏡、分光鏡、截止濾光鏡、帶通濾光鏡、帶止 遽光鏡等等。而電腦的出現，；j;但使光學薄膜設計（電腦輔 助軟艎）更為方便，且光學薄膜的相關研究更是一日千裡。 31 M350037 至今，光學薄膜製作的困難點已經很少出現下設計上，只 要特性要求合理，總是能設計㈣用❹層駭構，關鍵 的問題在於薄膜製鍍工藝的改進，如何精確地控制每一層 的厚度和折射率，以得到期望的光學性質和機械特性，甚 至考量製作的量產化及成本的降低，另外如薄膜材料的開 發、先進艘膜技術的開發與薄膜的量測等，皆為薄膜工程上 所要探討的重要課題。 本創作的鍍介電質膜廣角反射鏡10是以電腦輔助的光 學薄膜設計製作的多層薄膜架構。 至於，鍍介電質膜廣角反射鏡10的「鏡子」的鏡面效果， 反射率越大則鏡面效果越好。但是，提升反射率就會降低穿 射率。 如果降低穿射率後在一般的環境下會影響成像品性變 差，這就要再提升穿透率。提升穿透率就降低鏡面的效果。 要「提升鏡子的鏡面效果」以及要「得到最佳成像品質」 是不容易同時兼顧的。如前面所述之，入射光等於反射光加 上透射光。若入射光為一定，則反射光與透射光成反比，反 射光增加透射光就減少，透射光增加反射光就減少。 32 M350037 再回顧上面如由圖三與圖三A光譜製作的樣品中其穿射 率為20%，是本創作較佳實施例。但並非限制在剛好2〇%。 在實際測試環境中穿射率在20%與23%之間並無多大差異。 甚至於在大賣場、銀行内部、大飯店等的環境下測試結果發 現穿透率在20%與40%之間也並無多大的差異，這完全端 視環境的光照度而論。 就一般實驗而言’反射率大於穿透率就可顯示出有「鏡 子」的鏡面效果。當然，這要在有黑色或深色的背景才能顯 示出來。也就是說，穿透率在10%與40%之間是一般環境下 是「可形成鏡面效果」的較適當範圍。 穿透率在10%不是不行，僅是在環境低照度（約 lOLux)下使用者對成像品質變差而已。但是，對於最近出 品的高解析度低照度的CCD攝影機來說，例如，韓國三星 Samsung編號SDB-40規格顯示以F1.2鏡頭彩色最低照度 為0· 3Lux、黑白（夜間）最低照度為〇· 〇〇2Lux，這在穿透率 在10%時的確可攝取到令人滿意的品質，這是屬於高階產 品。對於低階的CMOS例如10萬像素（Pixels)而言，要達 到滿意的品質其穿透率約在40%或以上，這種低階的 CMOS已逐漸退出市場。對CMOS例如30萬像素者經過部 33 M350037 份參數的調整穿透率在20%時在環境照度約1〇〇Lux下確也 可攝取到令人滿意的品質。 請參閱圖五為自動提款機上安装本裝置之實施示意圖。

大小的鏡面（左右顛倒）影像。當一反射鏡呈現圓弧凸狀時 可以反射比一反射鏡呈現平面狀更寬廣的正面（有變形失 真）影像。 所以這種具圓弧凸狀的反射鏡可稱為廣角反射鏡。 • 例如在圓直徑同為五公分的相同尺寸下，廣角反射鏡 比平面反射鏡取得更寬廣的反射影像。 廣角反射的到底要多「廣角」？在同一尺寸下廣角反射 的圓弧凸狀越凸（彎曲率越大）其可視角度相對較廣。廣角 反射的可視角度越廣其成像相對越失真。廣角反射的可視角 度對自動提款機前的第一提款人來說，設定在約90度至 120度對可取得很好的視野。 35 M350037 所以’本裝置「自動提款機的廣角反射攝影鏡裝置」的 表面字義中；其「廣角」的意思是區別於一般平面反射鏡具 有較大的反射角度、其「攝影鏡」的意思是指具有「攝影」與 「鏡子」的功能組合物》其中，彩色攝影機組20具有「攝影」 的功能禮介電質膜廣角反射鏡1〇具有「鏡子」的功能。而把 鍍介電質膜廣角反射鏡10與彩色攝影機組20組合，則除了 兼具有「攝影」與「鏡子」的組合功能外，鍍介電質膜廣角反 射鏡10也具有保護彩色攝影機組20與彩色攝影機組20也 具有延伸彩色攝影機組20的監視，使鍍介電質膜廣角反射 鏡10與彩色攝影機組20組合達到互補的功效。 一般傳統的廣角反射鏡，例如道路用的大型廣角反射 鏡與機車（摩托車）用的小型廣角反射鏡等若與彩色攝影 機組20組合則無法具有「攝影」與「鏡子」的組合功能，因為 一般傳統的廣角反射鏡無法或不容易穿透可見光，使彩色 攝影機組20無法成像。 其中，鍍介電質膜廣角反射鏡10除了具有「鏡子」的功 能以外，還兼具有與先前技術的鍍金屬膜廣角反射鏡所揭 露「可穿透可見光攝影成像」的功能。例如，「中華民國新型 專利第Μ 326646號鍍铭半球型罩攝影機裝置」。 36 M350037 前面說出，鍍金屬膜廣角反射鏡對紅外又有很高的吸 收帶（不利紅外夜視），所以鍍介電質膜廣角反射鏡10相 對於鍍金屬膜廣角反射鏡具夜視效率。如果不考慮其夜視效 率，考慮一般金屬反射膜製備工藝簡單的優點，工作的波 長範圍大反射帶比較寬，雖然有光損耗大的缺點，但在反 射率有55%(也有鏡面高反射效果)與穿透率有20%的鍍金屬 膜廣角反射鏡，在實際實施應用於環境照度充裕的銀行内 設置的自動提款機上，如這種具有反射率55%與穿透率20% 的鍍金屬膜廣角反射鏡也可取得不錯的效果。 請回顧如圖一所示，介面體（黑色圓形底盤）30支持 著鍍介電質膜廣角反射鏡10與彩色攝影機組20，使艘介電 質膜廣角反射鏡10、一彩色攝影機組20、與一介面鱧30等 三部份組成一本裝置100的產品。 對於本裝置100產品的實際應用上，再請回顧如圖五所

周圍面上。如此，就簡單完成把本裝置1〇〇安裝在提款機台 200上（如圖五所示）。 對於本裝置100產品的另一個實際應用上，如圖五所示 的提款機台200，在經過設計後可直接將本裝置1〇〇的鍍介 電質膜廣角反射鏡10與彩色攝影機組20，分別固定鎖在提 款機台200本體的外部與内部，而直接省略黑色圓形底盤 30者，也可達成相同效果。 因此’介面體30是指可支持固定鍍介電質膜廣角反射

Optical film thickness = 1. 0500 plated dielectric film wide-angle mirror 1 〇 sample 2 and plated dielectric film wide-angle mirror 10 samples, the two colors are not exactly the same, but they all show bright specular reflection, It looks like a real mirror mirror. As shown in Figure 3, the transmittance increases from 20% to about 95% above the spectral wavelength of 740 nm. This shows that the plated dielectric film wide-angle mirror 1 〇 sample 2 can transmit about 20% of visible light and has a high transmittance to infrared. Briefly, the color photography unit 20 of the sampled dielectric film wide-angle mirror 10 is used to capture infrared images in an infrared environment. The color film unit of the plated dielectric film wide-angle mirror 10 is equipped with a color photography unit 2〇, and it is not possible or easy to capture infrared images in an infrared environment. 26 M350037 In other words, when the ambient illuminance of the cash dispenser is insufficient, the plated dielectric film wide-angle reflector ίο sample 1 has a relatively poor imaging effect. Plating Dielectric Films Wide-angle mirrors 10 sample 2 can see clear infrared images in the infrared-assisted light source. However, almost all ATMs around the world are set up to have sufficient ambient light to facilitate the withdrawal of cash by the cashier, or to provide a safe environment for the cashier due to sufficient lighting. A sample of the key dielectric film wide-angle mirror 10 is already available. For the environment is not long time in the case of sufficient illumination, it is necessary to add infrared LED light source 22, for example, as shown in Figure 2B, it is more suitable for plating dielectric film wide-angle mirror 1G sample - switch to dielectric film wide angle The mirror 10 sample 2 is then matched with an auxiliary infrared source. In the light diagram curves of Fig. 2 and Fig. 2A, the transmittance between the visible light range 4〇〇 and (10) is about the muscle, and the curve is not a complete-sequence straight line. Generally, the larger the refractive index, the greater the reflectance. In the visible light part, the refractive index of different colors is changed from small to large and belongs to the positive dispersion case (n_d-P sion), but the variation range is small, as shown in the spectrum of the three and three figures, the variation of the S-degree (non-smooth straight line) ) Fine, the photographic image of this device 27 M350037 quality (color shift) has no effect on the human eye, so it is not necessary to increase the number of coating layers to correct. As shown in the spectrum of Figure 3 and Figure 3A, because both sample 1 and sample 2 have 20% visible light penetration, theoretically in Figure 1 at an oblique angle (non-frontal angle of incidence of 0 degrees, such as 45 degrees of view) The human eye 10a under the light is close to look closely, and the color photography unit 20 after plating the dielectric film wide-angle mirror 10 is seen. As previously stated, because the black circular chassis 30 absorbs and scatters and then penetrates through 20% of the plated dielectric film wide-angle mirror 10, it finally penetrates almost zero. This makes the donor's human eye l〇a almost invisible to the color film unit 20 after plating the dielectric film wide-angle mirror 10. If the plated dielectric film wide-angle mirror has a large arc angle (for example, a semi-circular shape), the re-reflected light penetrating the plated dielectric film wide-angle mirror 10 is not absorbed and scattered by the black circular chassis 30. • A portion of the light that is transmitted through the plated dielectric film wide-angle mirror 10 causes the cashmer's human eye 10a to faintly see the color film unit 20 after plating the dielectric film wide-angle mirror 10. In the case of thin film optics, it is easy to obtain a desired transmittance T% by a vector method or an admittance trajectory method on a multi-layered quarter-wave film stack in which the refractive index is alternately changed on an optical grade substrate. In theory, it can also be proved that 28 M350037 uses the same multi-layer layer, and the quarter-wave film stack has higher reflectivity than the non-quarter-wave film stack. The more the number of layers, the greater the R% reflectivity. That is to say, it is easy to control the split ratio of penetration and reflection. At present, the available film materials have a high refractive index in the visible light region of less than 2.4 and a low refractive index of 1.35 or more, so the width of the high reflection band of the single quarter-wave film stack is limited. Therefore, in order to satisfy the present embodiment, it is possible to have a wide reflection band like a metal film in the visible light region, and it is necessary to widen the high-reflection band of the full dielectric film. One of the methods of broadening is to increase the concentration of each layer of the film system regularly (depending on the number of steps or the number of steps) so that there is enough film at any wavelength in a wide area. The layer, whose optical density is also close enough to a quarter wave. However, the reflectivity of the highly reflective region thus produced has many declining ripples which must be optimized by optimization. Other methods include adding a quarter-wave film stack with a shorter center wavelength to the other quarter-wave film stack. The design of the coating can basically start with the standard membrane system. For example, the high mirror is designed on the basis of a quarter-wave membrane stack regardless of the width or the single or double wave number. 29 M350037 When the initial design fails to meet the optical performance of the requirements, it is optimized or synthesized using current commercially designed computer software. Some optimizations use mathematical techniques and are constantly being improved. For example, the most commonly used are the Simplex method, the Least-square fit or damped least squares, and the synthesis method. In this embodiment, the designed parameters of each film layer are re-committed to the manufacturer. The dielectric film wide-angle reflector 10 is shown in Fig. 3 and Fig. 3A by vacuum evaporation. The same film design produces different spectra in different brand coating opportunities. The heating distribution temperature, film replacement, and substrate shape of the same machine affect the characteristics of each coating. When mass-produced dielectric film wide-angle mirrors are used, it is economical to use a dedicated machine. Please refer to Figure 4 for the relationship between the reflectance R% of the film and the optical thickness. • It is known from the optical film interference phenomenon that when the light is incident vertically (the front side is 0 degrees) on the single layer film' and the optical thickness Nd (which is the product of the film refractive index and the film thickness) is (21«)/2), again (), (34〇/2>.. The film's reflection intensity against the wavelength is constant; if the optical thickness Μ is (λ〇/4), (3 0/4), (5λ〇/4)...' the reflectance will be a maximum value or a minimum value, and the value is determined by whether the refractive index η of the film is greater than or less than the refractive index of the substrate when n>nS, the reflectance is a maximum value, and at n < nS, the reflectance is a minimum value, As shown in Figure M350037. As can be seen from Figure 4, the optical thickness of one layer is an odd multiple of one-fourth of the wavelength of the incident light, so that the reflected wave forms destructive interference, and the reflectivity is reduced. The reflectance of the wavelength is not 〇, so in order to obtain a wide reflectance in the visible light range, it is usually a multi-layered structure, and the appropriate reflectance can be obtained by appropriately selecting the refractive index of the film layer and the film layer design. A film with a H-light particle size of four-wavelength and a low refractive index, which can be used as an anti-reflection To reduce the surface reflectance, for example, a single layer of magnesium fluoride (b匕7, n = 1.38) is plated on the surface of glass (BK7' η = 1.53), which is a simple structure of anti-reflection film. Coating the surface of the glass with a material with a sufficiently high refractive index will greatly increase the reflectivity of the glass surface, so the film can be used as a good beam splitter, a single layer of titanium dioxide (Ti02, η = 2.2) or zinc sulfide. (znS, η = 2 35) Thin film is often used for this purpose, and the reflectivity is about 30%. Basically, the superposition of a single layer film is a multilayer film. When a multilayer film is used, high and low refraction can be used according to our needs. Rate film stacking, making a variety of film designs to produce the optical properties we require. Commonly used as anti-reflectors, high mirrors, beamsplitters, cut-off filters, bandpass filters, with stagnation Light mirrors, etc., and the emergence of computers; j; but the optical film design (computer-assisted soft palate) is more convenient, and the related research of optical film is even more and more. 31 M350037 So far, the difficulty of optical film production The point is already very With less design, as long as the characteristics are reasonable, it can always be designed. (IV) With the layer structure, the key problem is the improvement of the film plating process, how to accurately control the thickness and refractive index of each layer to obtain the desired optics. The nature and mechanical properties, even the mass production and cost reduction of the production, and the development of thin film materials, the development of advanced membrane technology and the measurement of thin films are all important topics to be explored in thin film engineering. The plated dielectric film wide-angle mirror 10 is a multi-layer film structure designed by computer-assisted optical film. As for the mirror effect of the "mirror" of the dielectric film wide-angle mirror 10, the greater the reflectivity, the mirror effect The better, however, increasing the reflectance will reduce the penetration rate. If the penetration rate is lowered and the image quality is deteriorated under normal circumstances, it is necessary to increase the penetration rate. Increasing the penetration reduces the effect of the mirror. It is not easy to "enhance the mirror effect of the mirror" and "get the best image quality". As described earlier, the incident light is equal to the reflected light plus the transmitted light. If the incident light is constant, the reflected light is inversely proportional to the transmitted light, and the reflected light increases the transmitted light to decrease, and the transmitted light increases the reflected light to decrease. 32 M350037 Recalling the above example, the penetration rate of 20% in the samples prepared from the spectra of Figures 3 and 3A is a preferred embodiment of the present invention. But it is not limited to just 2%. In the actual test environment, the penetration rate is not much different between 20% and 23%. Even in the environment of hypermarkets, banks, hotels, etc., it is found that the penetration rate is not much different between 20% and 40%, which is completely dependent on the illuminance of the environment. For the general experiment, the reflectance is greater than the transmittance to show the mirror effect of the "mirror". Of course, this can only be shown in a black or dark background. That is to say, the penetration rate between 10% and 40% is a relatively suitable range of "mirror-forming effect" in the general environment. The penetration rate is not 10%, only the user's image quality deteriorates under low ambient light (about lOLux). However, for the recently produced high-resolution low-illuminance CCD camera, for example, the Korean Samsung Samsung SDB-40 specification shows that the minimum illumination of the F1.2 lens is 0·3 Lux, and the minimum illumination of black and white (night) is 〇· 〇〇2Lux, which does have a satisfactory quality when the penetration rate is 10%, which is a high-end product. For low-order CMOSs such as 100 megapixels (Pixels), low-order CMOS has gradually withdrawn from the market to achieve satisfactory quality with a penetration rate of about 40% or more. For a CMOS, for example, a 300,000-pixel person through the 33 M350037 parameters, the adjusted transmittance at 20% can also be satisfactorily obtained at an ambient illumination of about 1 〇〇 Lux. Please refer to Figure 5 for a schematic diagram of the installation of the device on the cash dispenser. Please refer to 囷五A for a list of cashiers. Please refer to Figure 5B for a schematic diagram of the typewriter entering the password. For example, the round five automatic cash dispenser includes a banknote opening 41, an operating keyboard Lu 42, a device 1 〇〇 (only one plated dielectric film wide-angle mirror 10 is seen on the cymbal), and a cash machine Taiwan 200. Usually when there are multiple people queuing in front of a cash machine 2, as shown in Figure 5a, 'the first lender (the person who queued the front) operates the password as shown in Figure 5B' - The cashier is afraid that the person who is behind the queue will see the digital password that he has pressed on the operating keyboard 42. At this time, the first drawer can use the plated dielectric horn mirror 10 set by the right (five) side. The reflection can clearly see whether others behind the queue are "sneaked." In some financial difficulties, sometimes when the first-cash operator successfully completes the operation on the operation panel 42, the moment when the banknote is taken out of the banknote 41 may be taken away by others who are lined up. At this time, the first cashier can be taken away by the color photography unit 20 behind the plated dielectric film wide-angle mirror 1Q disposed on the right front side, and the video is searched and found. 34 M350037 As shown in Figure 5, in the cash machine station 200 management unit (such as the banker) can also be used by the right front of the plated dielectric film wide-angle mirror 1 〇 behind the color camera unit 20, General environmental photography monitoring is performed around the front of the cash dispenser 200. The first cashier should clearly see the images of others queued behind him. The image range of the image seen is related to the shape and size of the plated dielectric film wide-angle mirror. Generally, when a mirror is flat, it can reflect a mirror-like (left-right reversed) image of a general size. When a mirror exhibits a convex arc shape, it can reflect a wider front (deformed distortion) image than a mirror. Therefore, such a circular convex mirror can be called a wide-angle mirror. • For example, in the same size with a circle diameter of five centimeters, a wide-angle mirror produces a wider reflection image than a flat mirror. How much "wide angle" does wide-angle reflection have? The convexity of the arc of the wide-angle reflection at the same size is convex (the greater the bending rate), and the viewing angle is relatively wide. The wider the viewing angle of wide-angle reflection, the more distorted its imaging is. The angle of view of the wide-angle reflection is good for the first cashier in front of the cash dispenser, setting a range of about 90 to 120 degrees. 35 M350037 Therefore, the "wide-angle reflection mirror device of the "automatic teller machine" of this device has the surface meaning; the "wide-angle" means that it has a larger reflection angle than the general plane mirror, and the meaning of the "photographic mirror" It is a functional composition having "photography" and "mirror". Among them, the color photography unit 20 has a function of "photography", and the function of the wide-angle reflector 1 has a "mirror" function. In combination with the plated dielectric film wide-angle mirror 10 and the color camera unit 20, in addition to the combined function of "photography" and "mirror", the plated dielectric film wide-angle mirror 10 also has a protective color photography unit. The 20 and color photography unit 20 also has the monitoring of the extended color camera unit 20 to achieve a complementary effect of combining the plated dielectric film wide-angle mirror 10 with the color camera unit 20. Conventional wide-angle mirrors, such as large wide-angle mirrors for roads and small wide-angle mirrors for locomotives (motorcycles), cannot be combined with color photography unit 20 to have a combination of "photography" and "mirror" because Conventional wide-angle mirrors are unable or difficult to penetrate visible light, rendering color photography unit 20 impossible to image. Among them, the plated dielectric film wide-angle mirror 10 has the function of "mirror", and also has the function of "transparent visible light imaging" as disclosed in the metallized film wide-angle mirror of the prior art. For example, "The Republic of China new patent No. 326646 plated Ming hemisphere cover camera device". 36 M350037 As stated earlier, the metallized wide-angle mirror has a very high absorption band for infrared (unfavorable infrared night vision), so the plated dielectric film wide-angle mirror 10 has a night vision efficiency relative to the metallized film wide-angle mirror. . If the night vision efficiency is not considered, considering the advantages of the general metal reflective film preparation process, the working wavelength range is large, and the reflection band is relatively wide. Although there is a disadvantage of large optical loss, the reflectivity is 55% (there is also a specular high reflection effect). ) A metallized film wide-angle mirror with a penetration rate of 20% is actually applied to an automatic cash dispenser installed in a bank with sufficient ambient illumination, such as a reflectivity of 55% and a penetration rate of 20%. Metal-coated wide-angle mirrors can also achieve good results. Referring back to FIG. 1, the interface body (black circular chassis) 30 supports the plated dielectric film wide-angle mirror 10 and the color camera unit 20, and the dielectric film wide-angle mirror 10 and a color camera unit 20 are provided. The product of the device 100 is composed of three parts, such as an interface 鳢30. For the practical application of the device 100, please refer back to Figure 5, which is to dig a hole of appropriate size at the top right of the cash machine 200 for insertion into the color camera. Aluminum round tube. Then, a strong double-sided tape (for example, 3M double-sided tape) is adhered to the back of the black circular chassis 30, and the aluminum tube of the color photography unit 20 is inserted into the round hole, so that the other side of the double-sided tape is adhered to the cash machine. 200 round holes around the surface. That is to say, use a 37 M350037 double-sided tape to adhere the back of the black circular chassis 3〇 to the surrounding surface of the round hole of the cash machine platform 200. Thus, the device 1 is simply mounted on the cash dispenser 200 (as shown in Figure 5). For another practical application of the device 100 product, the cash dispenser table 200 shown in FIG. 5 can be directly designed to directly apply the plated dielectric film wide-angle mirror 10 and color photography unit of the device. 20, respectively, the lock is fixed on the outside and the inside of the body of the cash dispenser 200, and the black circular chassis 30 is directly omitted, and the same effect can be achieved. Thus, the "interface 30" refers to a portion of the black circular chassis and the fifth dispensing machine 200 that can support the fixed-plate dielectric film wide-angle mirror 10 and color photography unit 2, for example. 1 and FIG. 5, the plated dielectric film wide-angle mirror lens 10 is disposed at the opening of the interface body 30 side, and the opening is mainly for the incident lens L20 through the 'color photography unit 2 〇 photographic lens 21 is disposed in the interface ship 30. The photographic lens 21 of the color camera unit 2 faces the inner surface β of the wide-angle mirror lens 10, and the incident light L20 penetrates the plated dielectric film wide-angle mirror lens 1 and can directly enter the photographic lens of the color camera unit 20. 21 imaging. 38 M350037 The above embodiments illustrate the implementation of the present invention, and those skilled in the art can readily appreciate the other advantages and effects of the present disclosure from the disclosure herein. The present invention may also be implemented or applied by other different embodiments. The details of the present specification may also be based on different viewpoints and applications, and various modifications and changes may be made without departing from the spirit of the present invention.
