不同光學產品因應用的不同,所以其在檢測上也需要提供一類似且相應的測試條件,例如包括視角(FOV, Field of View)及物距,如何在一有限空間上提供可滿足不同物距及視角等架構實為重要,如一般市面相機鏡頭、監視器或望遠鏡等物距是幾米或上千米,而視角則可能從2度到165度甚至更大等。 Different optical products have different applications, so they also need to provide a similar and corresponding test condition for detection, such as FOV (Field of View) and object distance. How to provide it in a limited space to meet different object distances The structure and the angle of view are really important. For example, the object distance of general market camera lenses, monitors or telescopes is a few meters or thousands of meters, and the angle of view may be from 2 degrees to 165 degrees or even greater.
圖1顯示習知技術之可縮短物距的光學模擬裝置的示意圖。圖1為臺灣公開第201409007號所揭示的一可縮短物距的技術。請參閱圖1,可縮短物距的光學模擬裝置3,用以將一測試屏幕2的影像投射於置於光學模擬裝置3出瞳位置的待測鏡頭1,而能夠使用一較短的物距u,讓該待測鏡頭1擷取到一較大的虛擬屏幕2’。依據圖1的習知技術,可針對遠物距,利用中繼鏡頭(Relay Lens)縮短實際距離,但類似架構對廣角或魚眼鏡頭或影像模組而言,中繼鏡頭的設計及製作上有相當的困難度。

圖2顯示習知用以檢測鏡頭之鏡頭檢測裝置的示意圖。圖2的技術為無限-有限距共軛系統。如圖2所示,鏡頭檢測裝置100包含一標靶110、一光源120、一待測鏡頭130、多個望遠影像模組140及一弧面軌道150。光源120的光線穿透標靶110,標靶110上刻有所需分析的圖案,隨後光線再經由待測鏡頭130投影至一望遠影像模組140。望遠影像模組140包含一望遠鏡頭141及一影像感測器142。望遠鏡頭141提供一無窮遠物距,影像感測器142則取得包含標靶110的圖案的影像,並利用電腦及軟體演算(未圖示)得知該影像品質。於圖2所示的鏡頭檢測裝置100,可安裝有多組的望遠影像模組140,以便同時測得不同視角(field of view,FOV)之影像品質,且望遠影像模組140視需求也可以沿弧面軌道150的弧面移動即可測得另一不同視角的影像品質,此架構優點為對廣角鏡頭而言限制較少。

圖3顯示圖2習知技術之鏡頭及影像模組檢測裝置的一使用狀態的示意圖。如圖3所示,依據圖2習知技術,將多個望遠影像模組140置於弧面軌道250的中間部分,用以量測待測光學裝置230的中心部分的光學性質時,因望遠影像模組140間的機構干涉,只能夠量測大於特定規格的視角。習知技術的缺點在於當視角小於特定規格時則而無法量測。

潛望式鏡頭(Periscope Lens),是一種利用光線反射原理所製作的光 學儀器。潛望式鏡頭,可以包含有“潛望鏡式變焦”功能,俗稱“內變焦”功能,由於其光學變焦是在機身內部完成,所以可以很容易安裝濾鏡,無需額外安裝鏡頭筒。由於鏡筒長度固定不變,可以非常方便地進行密封處理,所以密封性會更好。隨著科技的不斷進步,潛望式鏡頭已經不僅僅只應用在數位相機上,在一些手機產品上也得到了廣泛應用。 Periscope Lens (Periscope Lens) is a kind of light made by the principle of light reflection Learn instrument. The periscope lens can include the "periscope zoom" function, commonly known as the "internal zoom" function. Since the optical zoom is done inside the body, the filter can be easily installed without the need for an additional lens barrel. Since the length of the lens barrel is fixed, the sealing process can be carried out very conveniently, so the sealing performance will be better. With the continuous advancement of technology, the periscope lens has not only been used in digital cameras, but has also been widely used in some mobile phone products.
依據本發明一實施例,提供一種光學檢測裝置其能夠用以檢測潛望式鏡頭。依據本發明另一實施例,提供一種光學檢測裝置,其具有一可切換的轉向光路結構。較佳地,該光學檢測裝置能夠兼顧一般的鏡頭以及一潛望式鏡頭的檢測功能。更具體的說明,如下。 According to an embodiment of the present invention, an optical detection device is provided which can be used to detect a periscope lens. According to another embodiment of the present invention, an optical detection device is provided, which has a switchable turning light path structure. Preferably, the optical detection device can take into account the detection functions of a general lens and a periscope lens. A more specific description is as follows.
圖4顯示本發明一實施例之光學檢測裝置的示意圖。如圖4所示,光學檢測裝置200用以檢測一第一待測光學裝置231,其包含一光源220、一標靶210及一影像感測模組340。於一實施例中,可以更包含有一調整軸模組280。於另一實施例中,可以更包含有一計算機289。於一實施例中,光源220的光線穿透標靶210,標靶210上刻有所需分析的圖案,隨後光線再經由第一待測光學裝置231投影至一影像感測模組340。影像感測模組340用以擷取一包含標靶210之圖案的影像。於一實施例中,影像感測模組340包含多個望遠影像模組240及多個影像感測器245。詳言之,影像感測模組340的影像感測器245擷取一包含標靶210之圖案的影像,而其望遠影像模組240能夠形成一無窮遠物距並擷取一影像,更具體而言望遠影像模組240包含一望遠鏡頭241及一影像感測器242。望遠鏡頭241提供一無窮遠物距,影像感測器

In an embodiment, the first optical device to be tested 231 may be an optical device with a non-linear optical path, preferably a periscope lens. In FIG. 4, the optical path of the first optical device to be tested 231 is non-linear, and the light enters from the left side and exits from the upper side, that is, the optical path turns 90 degrees. Therefore, the
調整軸模組280連接於標靶210,用以調整標靶210的方位。於一實施例中,調整軸模組280可以包含至少一維度調整裝置,較佳的情況是例如包含一第一維度調整裝置281及一第二維度調整裝置282,分別用以調整第一維度及第二維度的值,其中第一維度相異於第二維度。於一實施例中,第一維度或第二維度可以為x線性軸、y線性軸、z線性軸、第一旋轉軸及第二
旋轉軸其中之一。於一實施例中,調整軸模組280為一種五軸調整裝置,其具有可調整的3個線性軸及2個旋轉軸。計算機289可以為電腦、個人電腦、平板電腦、筆記型電腦和智慧型手機等能夠進行計算的裝置。較佳地,可以為根據一系列指令指示並且自動執行任意算術或邏輯操作序列的裝置。於一實施例中,調整軸模組280亦可以耦接於計算機289,計算機289可以控制調整軸模組280,使標靶210位於適當的檢測位置。
The
一實施例中,光學檢測裝置200可以更包含一弧面軌道250。如圖4所示,弧面軌道250的中間部分呈現中空狀態,藉以該些影像感測器245及標靶210位於一第一光路狀態時,讓光源220的光線通過該中間部分,最後再進入至該些影像感測器245。更具體而言,弧面軌道250包含一第一軌道251及一第二軌道252,第一軌道251及第二軌道252間隔著一預定距離,使得弧面軌道250的中間部分呈現中空狀態,而讓光源220的光線通過,最後再進入至該些影像感測器245。依據習知技術,當視角小於特定規格時無法量測,然而依據前述設計,即使視角小於特定規格,亦能夠進行量測。
In an embodiment, the
一實施例中,光學檢測裝置200可以更包含一延伸臂273,其連接並固定望遠影像模組240a,能夠選擇性地移動望遠影像模組240a使其延伸至弧面軌道250之中間。依據本實施例,弧面軌道250的中間部分呈現中空狀態,會有中間部分無法用望遠影像模組240進行量測的問題。有鑑於此,於一實施例中,使延伸臂273連接至該些望遠影像模組240中的位於弧面軌道250之中間的一望遠影像模組240a,延伸臂273用以移動望遠影像模組240a,使望
遠影像模組240a選擇性地位於弧面軌道250的中間部分及不位於中間部分。更具體而言,在第二光路狀態時,望遠影像模組240a更位於弧面軌道250的中間部分,使標靶210不面向該些影像感測器245;而在第一光路狀態時,望遠影像模組240a不位於弧面軌道250的中間部分,使標靶210面向該些影像感測器245。不同於習知技術,本實施例利用手動或電動馬達或類似的換位機構,使中心的望遠影像模組240a可位移,較佳地位移至不遮到較小視角的有效光路,而較小視角之檢測改由以實際物距搭配影像感測作相關光學品質檢測。

一實施例中,光學檢測裝置200可以更包含一感測器固定座291及一距離調整裝置292。該些影像感測器245設於感測器固定座291上,且感測器固定座291連接於距離調整裝置292,距離調整裝置292用以改變該些影像感測器245與第一待測光學裝置231間的距離。一實施例中,感測器固定座291能
夠在距離調整裝置292上移動,較佳地在距離調整裝置292的長軸上移動,如此,能夠改變該些影像感測器245與第一待測光學裝置231間的距離。當將中繼鏡頭260移除或更新不同的中繼鏡頭260時,可以調整該些影像感測器245與第一待測光學裝置231間的距離,以將該些影像感測器245設置在適當的位置上。
