Description

[0001] DOT SIGHTING DEVICE [0002]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dot site apparatus, and more particularly, to a dot site apparatus capable of preventing exposure of a user's position by advancing a light ray emitted from a dot-
The optical zoom magnification (low magnification) dot sight sight can be easily and quickly aimed, and it is very convenient to aim at an emergency situation or near.
It is possible to save time spent in alignment of the conventional collimation line, and the collimation itself is sufficient to place a dot image on the target, and thus it is possible to have a margin for securing the field of view.
However, in the conventional dot sight sighting device, the dot sighting occurrence portion may be detected by the other party as the light rays of the light source of the dot sight generating portion pass through the reflecting mirror that forms the virtual image of the dot sight mark and progress toward the opposite side in the target direction, A problem has arisen that the position of the optical fiber is exposed.
In particular, in an environment where the periphery becomes dark (at night or when the surrounding light becomes dark), exposure of this light source becomes noticeable to the other party first, so that the priority of shooting can be missed and the advantage of the dot site can not be maintained.
1, the light source of the dot visual-mark generating unit 1 transmitted through the reflector 2 is not seen in the optical axis direction (direction A) but is seen in the direction B slightly out of the optical axis There are disadvantages. That is, in the conventional barrel type dot site, since the dotted-eye mark generating unit 1 is arranged in the barrel, the dotted-eye mark generating unit light source may not be seen in some directions (direction above the A direction in FIG. 1) , And the light source of the dot visual indicator is visible in the other direction (the direction lower than the direction A in FIG. 1, particularly the direction B).
Similarly, in the conventional open type dot site as shown in FIG. 2, the light source of the dot visual mark generating unit 1 transmitted through the reflector 2 is seen from the target facing the dot visual mark generating unit.
As shown in FIG. 3, the dot site using the beam splitter transmits the dot pattern of the dot pattern on the target side because the light source of the dot pattern generating unit 1 reflected by the beam splitter 3 transmits the reflector 2, So that the position of the user can be exposed.
In other words, even in the case of a dot site using a conventional beam splitter, a part of the light rays of the light source of the dot visual mark generating unit is transmitted in the direction of the target viewed by the user, have.

Prior to the description, components having the same configuration are denoted by the same reference numerals as those in the first embodiment. In other embodiments, configurations different from those of the first embodiment will be described do.
Hereinafter, the dot site apparatus of the present invention will be described in detail with reference to the accompanying drawings.
In the first embodiment of the present invention, a dot site apparatus including a beam splitter, particularly, a structure in which a reflector is disposed between a user and a target as shown in FIG. 4 will be mainly described.
4 is a configuration diagram of a dot site apparatus according to the first embodiment of the present invention. 4, the dot site apparatus according to the first embodiment of the present invention includes an optical path changer 120, a dot sign generator 110, a reflector 130, (140) and a second optical filter (150). The optical path changing unit 120 is disposed between the user and the target and is provided between the optical path dot dot mark generating unit 110 and the reflecting mirror 130 and has an inclined surface 121 for reflecting and transmitting light rays .
The optical path changing unit 120 may be formed in the form of a beam splitter formed by joining two right-angle prisms. The optical path changing unit 120 may be formed of, for example, 50% reflection When the coating is applied and bonded, 50% is transmitted and 50% is reflected.
The coating of the sloped surface 121 of the optical path changing unit 120 is performed by reflecting the light of the dotted table provided from the dotted mark generating unit 110 toward the reflecting mirror 130 and then converting the reflected light from the reflecting mirror 130 A light ray of the dot-shaped table which is reflected back toward the portion 120 is transmitted toward the user, so that the light of the dot-shaped table is imaged on the dotted image on the retina of the user's eye.
In addition, a light beam provided from the forward target is sequentially transmitted through the reflecting mirror 130 and the slope surface 121 of the beam splitter so as to form an image on the external target on the retina of the user's eye.
The coating of the inclined surface 121 is a function of the transmittance of each wavelength for the wavelength of the visible light region (approximately 400 to 740 nm) when the user overlaps the image of the external target and the dotted table, It is preferable that the thin film has a deviation within 30% so that the color of the external target secured from the external target and its surroundings does not significantly change.
The optical path changing unit 120 may be a beam separating flat plate disposed in an inclined manner. In the case of a beam-splitting flat plate, transmission and reflection coating can be performed according to the amount of light required for at least one surface of a flat plate-like optical glass arranged obliquely. That is, when the A% reflective coating is applied, 100% of the incident light provided on the inclined surface 121 is transmitted and reflected by the A%.
The dotted-eye mark generating unit 110 includes a light projection reticle system, an RC LED system, or a pixel array, which is disposed on one side of the optical path changing unit 120 and includes a light source and a target mask, An OLED system in which the shape of the mask can be changed, or the like can be adopted.
It is preferable that the dotted-eye mark generating unit 110 has a light source for providing a dotted line, that is, a first light component, having a specific range of spectrum toward the inclined surface 121.
For example, as shown in FIG. 5, a light source having a peak intensity of light intensity at a wavelength of about 655 nm, but having a characteristic that intensity of light gradually decreases as the distance from the wavelength of 655 nm May be configured as a light source of the dot sign generator 110.
5, it can be seen that the light intensity distribution in the 645 to 665 nm region is more than 50% of the light intensity distribution in the entire wavelength region.
The reflector 130 is disposed to face the inclined surface 121 of the optical path changing unit 120 and reflects the dot incident light reflected by the inclined surface 121 toward the inclined surface 121 to provide a dot The table provides a virtual image.
The reflector 130 is composed of a singlet or a doublet composed of two optical superlattices. When the reflector 130 is composed of a doublet as in the example of FIG. 4, It may be optically coated so as to be designed as a reflecting surface that reflects the target ray toward the inclined surface 121 and to form a light shielding portion on the surface of the reflecting mirror 130 on the target side.
When the reflector 130 is double-lit, the junction surface of the reflector 130 may be optically coated to serve as a reflection surface that reflects the dotted light toward the inclined surface 121 and the light shielding portion.
When the reflector 130 is a singlet, the first surface of the reflector 130 on the observer's side or the second surface of the target surface reflects the dotted surface light beam toward the inclined surface 121, And may be optically coated to serve as the light shielding part.
When the reflector 130 is singlet, the first surface of the reflector 130 on the observer side serves as a reflecting surface that reflects the dotted surface light beam toward the inclined surface 121, And the second surface may be optically coated to serve as the light shielding portion.
The first optical filter 140 is disposed on the optical path between the dot visual mark generator 110 and the optical path changing unit 120. The first optical filter 140 converts the first light component, which is the light provided from the dotted symbol generator 110, into a second light component, and stores the second light component into the light path conversion unit 120 do.
More specifically, the first optical filter 140 converts the first wavelength set in the spectral region of the dot-shaped light ray provided from the dot-sign generator 110 into a cut-on wavelength, A cut-on which reflects or absorbs most of light having a wavelength shorter than the first wavelength and transmits most of light having a wavelength longer than the first wavelength, .
Here, the cut-off wavelength refers to a wavelength at which the transmittance becomes 50% in a long pass filter, for example, and the cut-on wavelength in FIG. 6 is 650 nm.
9 (a) is a graph showing the transmittance versus wavelength of the long-pass filter. Specifically, referring to FIG. 9A, the cut-off wavelength generally represents a wavelength at which a transmittance of 50% is exhibited in the long-pass filter. At this time, most rays pass through the long-pass filter at the wavelengths higher than the cut-off wavelength, and most rays do not pass through the long-pass filter at the wavelengths below the cut-in wavelength. Here, the meaning of "most" means that light that does not pass through the filter among light having a wavelength higher than the cut-on wavelength, and light that is not blocked (reflected or absorbed) in the light having a wavelength below the cut-on wavelength.
However, if the slope of the transmittance relative to the wavelength is steep in the region near the cut-off wavelength, more rays among the rays in the wavelength region above the cut-off wavelength can be transmitted through the filter, and among the rays in the wavelength region below the cut- More rays can be blocked from passing through this filter.
Referring to FIG. 9 (a), as the wavelength becomes larger than the cut-off wavelength, the transmittance gradually increases from 50% to reach the maximum transmittance. Therefore, in order to pass all the rays above the cut-off wavelength, the slope of the transmittance relative to the wavelength should be steep in the region near the cut-off wavelength.
Referring to FIG. 9A, below the cut-off wavelength, as the wavelength decreases, the cut-off rate increases from 50% to the maximum cut-off rate. Therefore, in order to block all rays below the cut-off wavelength, the slope of the transmittance relative to the wavelength should be steep in the region near the cut-off wavelength. The first optical filter 140 may be configured as a long pass filter that transmits the majority of the light rays having wavelengths exceeding the cut-on wavelength and absorbs or reflects most of the light rays having wavelengths not exceeding the cut- And a long pass filter having a steep slope of transmittance versus wavelength in the region near the cut-off wavelength has a better blocking efficiency for a wavelength shorter than a cut-on wavelength and a transmittance efficiency for a wavelength longer than a cut-on wavelength.
Since the cut-off wavelength of the first optical filter 140 in this embodiment is 650 nm as shown in FIG. 6, most of light rays having wavelengths longer than 650 nm are transmitted through the spectrum region of the dot- , It can be seen that most of rays having a wavelength shorter than 650 nm can not be transmitted.
That is, a dot-shaped dotted line provided from the dotted-line mark generating unit 110 to the optical path changing unit 120 has a spectral wavelength as shown in FIG. 5. The dotted dotted dotted line is transmitted through the first optical filter 140, The light rays of wavelengths not exceeding the cut-off wavelength of 650 nm are largely reflected or absorbed and the light rays of wavelengths exceeding 650 nm, which is the cut-off wavelength, are mostly transmitted, Thereafter, a spectrum form as shown in FIG. 8 is obtained. That is, the second light component has a spectrum as shown in FIG.
The second light component converted by the first optical filter 140 is reflected by the inclined surface 121 of the optical path changing unit 120 to be directed to the reflecting mirror 130, And is directed toward the user, so that the ray of the dotted table is imaged onto the retina of the user's eye on the dotted table.
Meanwhile, as described above, a part of the second light component passes through the reflecting mirror 130 and is directed to a target located at an enemy. In the embodiment of the present invention, .
The second optical filter 150 is disposed between the user and the target and disposed between the reflector 130 and the target when the reflector 130 is disposed on the front surface (FIG. 4).
The second optical filter 150 has a second wavelength shorter than the first wavelength at a cut-off wavelength, and most of the light having a wavelength shorter than the second wavelength passes through the second optical filter 150, Most of the rays of large wavelengths perform blocking (reflecting) cut-off.
Here, the cutoff wavelength refers to a wavelength at which the transmittance becomes 50% in a short pass filter, for example, and the cutoff wavelength in FIG. 7 is 645 nm.
9 (b) is a graph of transmittance versus wavelength of a short path filter. Specifically, referring to FIG. 9 (b), the cutoff wavelength generally refers to a wavelength at which the transmittance is 50%. At this time, most of the light rays can not pass through this filter at the wavelengths above this cutoff wavelength, and most rays pass through this filter at the wavelengths below this cutoff wavelength. Here, "most" means light passing through the short-pass filter in the light having the wavelength longer than the cut-off wavelength, and light not passing through the short-path filter among lights having the wavelengths below the cut-off wavelength.
However, if the slope of the transmittance relative to the wavelength is steep in the region near the cutoff wavelength, more of the light rays in the wavelength range above the cutoff wavelength can not be transmitted through this filter, and among the light rays in the wavelength region below the cutoff wavelength So that more rays can pass through this filter.
The cut-off wavelength of the first optical filter 140, that is, the first wavelength is longer than the cutoff wavelength of the second optical filter 150, that is, the second wavelength, The invention is not limited thereto. For example, in the case of a filter having a good performance, that is, a filter having a steep slope of transmittance versus wavelength, the cut-off wavelength and the cutoff wavelength may be set to substantially the same wavelength.
However, the second optical filter 150 may be configured such that the wavelength band of the dot beam of the second light component transmitted through the first optical filter 140 (which has a distribution as shown in FIG. 8) 7, in order to transmit most of the wavelength band in the visible light region excluding the wavelength band (the wavelength band of the dot-like light ray after passing through the first optical filter 140) as shown in Fig. 8 Wavelength of 650 nm (see FIG. 7) of the cut-off wavelength of the first optical filter 140 can be set.
The second optical filter 150 may be formed by optically coating the reflective surface of the second optical filter 150 with a coating formed on the reflective surface of the reflector 130. In this case, It plays a role. The second optical filter 150 may be formed of a separate filter rather than a coating as shown in FIG.
In the above example, the first optical filter 140 is implemented by disposing a separate filter. However, the first optical filter 140 may also be implemented in a manner similar to the second optical filter 150, Or may be realized by a coating formed on the light exit surface of the generating part 110. [
In addition, the dotted-eye mark generating unit 110 may include a function of the first optical filter 140 internally.
In the above example, both the first optical filter 140 and the second optical filter 150 are disposed. However, when the light source of the dot-light-signal generating unit 110 is disposed at the first wavelength (The light having the wavelength shown in FIG. 8) having a longer wavelength than the first optical filter 140 (i.e., the cut-off wavelength), the first optical filter 140 may be omitted.
The second optical filter 150 may include a shot pass filter that transmits most of light having a wavelength not exceeding the cutoff wavelength and reflects most of the light having a wavelength exceeding the cutoff wavelength .
A shot pass filter having a steep slope of reflectance versus wavelength in the region near the cutoff wavelength has good transmission efficiency for a wavelength shorter than a cutoff wavelength and reflection efficiency for a wavelength longer than a cutoff wavelength.
Each of the first optical filter 140 and the second optical filter 150 may be a dichroic filter, a dielectric filter, a thin-film filter, An interference filter, a color filter, and the like.
The first optical filter 140 corresponds to a light converting unit for converting a first light component into a second light component, and the second optical filter 150 corresponds to a light blocking unit for blocking light of the second light component. .
According to the present embodiment, the light rays of the dotted-line table provided from the dotted-eye mark generating unit 110 are reflected on the inclined surface 121 of the optical path changing unit 120 and provided toward the reflecting mirror 130, The dot-like dotted line reflected by the dotted line 121 passes through the inclined surface 121 and is provided toward the user so as to form an image on the dotted line on the user's eye.
At this time, the dot-shaped marking light reflected from the inclined surface 121 of the optical path changing unit 120 toward the reflecting mirror 130 is cut-off by the first optical filter 140, And this dot-like marking light is reflected by the second optical filter 150 coated on the reflecting surface of the reflector 130, so that it can not pass through the second optical filter 150. Therefore, it is possible to prevent the dotted line from being transmitted to the counterpart of the forward target through the reflector 130, and the light of the dotted line table reflected by the second optical filter 150 is transmitted to the optical path changing unit 120 ) To be a virtual image of the dot mark and provide the dot mark to the observer.
7, the cutoff wavelength of the second optical filter 150 is set so that the cutoff wavelength of the second optical filter 150 is less than the cutoff wavelength, Since the long pass filter does not completely block light having a wavelength shorter than the cut-on wavelength of the long pass filter but partially transmits the light, the light passes through the short path filter the cut-off wavelength of the shot pass filter is set to 645 nm, which is shorter than the cut-off wavelength of the long pass filter of 650 nm, in order to prevent the shot pass filter from transmitting as much as possible. When the slope of the transmittance relative to the wavelength in the region near the cut-off wavelength of the long pass filter becomes more steeper and the slope of the reflectance relative to the wavelength in the region near the cutoff wavelength of the shot pass filter becomes steeper , The light transmitted through the second optical filter 150 by the dotted line will be very small by these two filters. Therefore, as long as the light of the dotted line is transmitted through the long pass filter and the shot pass filter, the cutoff wavelength of the shot pass filter is set to be long Allowing a closer access to the cut-off wavelength of the long pass filter.
The light beam (third light component) provided from the forward target is transmitted through the reflecting mirror 130 and the sloped surface 121 of the optical path changing unit 120 in order to form an image of an external target on the retina of the user's eye. do.
Since the cutoff wavelength of the second optical filter 150 is set to 645 nm, most of the wavelengths in the 400 to 645 nm region of the wavelength (about 400 to 740 nm) of the visible light region incident from the forward target are transmitted to the user So that the user can observe the front target and the peripheral portion thereof in a natural color.
In the present embodiment, the first optical filter 140 and the second optical filter 150 have a steep slope of the boundary between transmission and blocking or reflection with respect to the wavelength, As shown in the figure, a long pass filter and a short path filter having a characteristic of an optical filter (for example, a color filter) having a smooth slope of a boundary between transmission and blocking or reflection as shown in FIG. 140 and the second optical filter 150 may be configured.
Thus, a dot site apparatus having a beam splitter has been described with respect to the dot site apparatus according to the first embodiment of the present invention.
According to the dot site apparatus according to the first embodiment of the present invention described above, the light rays emitted from the dotted-eye mark generating unit 110 pass through the reflector 130 forming the virtual image of the dotted mark, It is possible to prevent the position of the user from being exposed to the other party.
In the first embodiment described above, the dotted-eye mark generating unit 110 is located below the optical path changing unit 120, and the reflector 130 is positioned between the user and the target, that is, The present invention is not limited thereto. For example, a structure in which the dot sign generating unit 110 is located below the light path changing unit 120 and the reflecting mirror 130 is located above the light path changing unit 120, And the reflector 130 is positioned below the optical path changing unit 120. The dotted-line mark generating unit 110 may be disposed on the optical path changing unit 120, The present invention is also applicable to a structure in which the reflector 130 is located on one of the right and left sides of the optical path changing unit 120. [
Next, a modification of the first embodiment will be described. The modified example described below relates to a dot site apparatus having a beam splitter and is different from the first embodiment in the shape, structure and arrangement of the first optical filter 140 and the second optical filter 150 .
This modification will mainly focus on the difference from the first embodiment, and the principle of preventing the light beam of the light source from being seen from the target side is applied similarly, and a detailed description thereof will be omitted.
10 is a configuration diagram of a dot site apparatus according to the first modification of the first embodiment of the present invention.
As shown in FIG. 10, a light beam having a longer wavelength than the cut-off wavelength is cut off and cut off, and the second optical filter 150, which transmits light having a wavelength shorter than the cutoff wavelength, The second optical filter 150 can block most of the dot-like light reflected by the inclined surface 121 of the optical path changing unit 120 from being transmitted through the reflecting mirror 130 . Therefore, it is possible to prevent the dotted line from being transmitted through the reflecting mirror 130 and provided to the opponent of the preceding target.
11 is a configuration diagram of a dot site apparatus according to a second modification of the first embodiment of the present invention.
In the second modification of the first embodiment of the present invention, as shown in FIG. 11, the reflector 130 for generating a dazzling virtual image is disposed at a position perpendicular to the optical axis between the user and the target. When the first optical filter 140 is disposed between the optical fiber 110 and the optical path changing unit 120 and the second optical filter 150 is disposed between the optical path changing unit 120 and the target, It is possible to block most of the dot-shaped light rays reflected from the slope 121 of the conversion unit 120 toward the target.
According to the arrangement structure of the first optical filter 140 and the second optical filter 150 of the second modification example described above, the facing surfaces of the first optical filter 140 and the optical path changing section 120 are parallel to each other .

That is, since the dot visual field-idle image formed by the first optical filter 140 composed of the curved surface is imaged at a position out of the range of the change in the user's eyes, the dot visual field- Can not be observed.
In the example of FIG. 13, the first optical filter 140 has a concave shape, but the present invention is not limited thereto, and it may have a convex shape, and in this case, the same similar effect can be obtained.
