Dot-sight device with polarizers

The dot site apparatus provided.

The characteristics of firearms, such as rifles and heavy machine guns, depend on whether you can quickly aim and fire at the target. In general, aiming firearms is achieved by aligning the line of sight with the scale. Aiming by alignment of the sight line at the tip of the barrel and the scale at the top of the gun body allows precise shooting depending on the ability of the observer using the firearm.

However, aiming at the scale and scale alone makes it difficult to align the line of sight even with small vibrations and tremors, and it is difficult to quickly aim in close range or urgent situations.

In other words, the aim shooting method requires a complicated process and time such as target capture and confirmation, line alignment, and aiming, and the scale and scale itself are so small that they are not only sensitive to small tremors in precise alignment, but also excessively sensitive. Attention to the alignment of the line of sight made it difficult to narrow the field of view necessary to deal with fire or emergencies, due to the focus on the scale and the scale itself rather than the target or the front situation.

Therefore, in order to solve these problems, a dot-site device has been proposed that uses a magnification-free or low-magnification lens for an optical sight, eliminates a complicated aiming line and simply uses only a aiming point (dot).

Optical magnification (low magnification) dot sight aiming devices are simple and quick to aim, and are very useful in emergency situations or at close range. Specifically, the time required for conventional line alignment can be saved, and the aiming itself is enough to place a dot virtual image on the target, and thus may have a margin of view. As a result, they can aim quickly and accurately, and they also have the necessary peripheral vision for context determination.

Specifically, in the conventional dot sight device 1 composed of a single lens reflector as shown in FIG. 1, the dot sight aiming device 1 is connected to the terminal 3 for arranging the firearm barrel through the fixing grill 11. After aligning the inside, the light beam emitted from the dot target generator 5 was reflected by the reflector 7 to position the virtual dot at the target point to confirm the aiming state. In general, the front surface of the reflector 7 (viewer direction of the aiming device) is coated to reflect the light beam irradiated from the dot target generator 5, and the curved surface of the front and rear surfaces of the reflector 7 is spherical or It is composed of aspherical surface.

The virtual image dot reflected through the reflector 7 is aimed at the target point to be gazed at a magnification through the protective window 9 so that the observer shoots when the dot virtual image from the dot target generator 5 coincides with the target. This can facilitate aiming.

However, in the case of a conventional dot sight aiming device, as shown in FIG. 1, the dot sight generating unit 5 is positioned outside the most part of the light beams reflected from the reflector so as to prevent the dot sight from occurring. The dot site observer was not detected by an external counterpart by making the light beam irradiated from section 5 not visible. In order to do this, however, the optical axis of the reflector is a principal ray, which is a representative ray of the reflected rays of the reflector forming a dot (a virtual image by the reflector of the dot timetable). (A1 in Fig. 2 (a); each A1 is generally one-half of each A2 formed by the path where the chief ray emitted from the dot sight generator is reflected by the reflector and travels to the dot-site optical axis). Should be inclined to

In this case, as shown in (a) and (b) of FIG. 2, the arrangement of the reflector not inclined with respect to the dot-site optical axis due to the arrangement of the reflecting mirror inclined with respect to the dot-site optical axis (FIG. 2 (a)) Finite ray aberration greater than FIG. 2 (b) occurs, affecting the parallax of the dot to be observed by the observer, and thus the size of the reflector (diameter) and the distance of the reflector from the dot target generator. When compared with the same structure, the arrangement of the reflecting mirrors inclined with respect to the dot-site optical axis (FIG. 2 (a)) has a larger parallax occurrence than the arrangement of reflecting mirrors not inclined with respect to the dot-site optical axis (FIG. 2 (b)).

This excessive occurrence of parallax is due to the initial alignment between the optical axis of the dot sight device and the bullet firing axis of the barrel and the shooting target point, and the more the observer's visual axis with respect to the shooting target point in the reflector is located off the dot site optical axis, It causes a problem that causes more and more errors. Therefore, excessive occurrence of parallax naturally lowers the accuracy of the target when using the dot site. In other words, a reflector that must provide a parallax within a certain limit (a parallax that causes the deviation of the position of the target point and the dot (dot image) to fall within the resolution limit of the eye or within a shooting error threshold). The size of is limited by the tilt angle A1 of the reflector.

However, in order to prevent excessive generation of parallax, the arrangement as shown in FIG. 2 (b) is preferable because the light beam irradiated from the dot sight generator can be detected by an external counterpart of the dot sight observer at a distance. I can't.

In addition, as shown in FIG. 3, the conventional dot sight has two radiuses of curvature of the reflector 5 according to D1 and D2 (two single reflection surfaces in the case of Singlet and four reflective surfaces in the case of Doublet (two of the two reflection surfaces). The radius of curvature is the same). (D1 is the horizontal distance in the dot-site optical axis direction from the optical center of the reflector 7 to the dot target of the dot target generator 5, and D2 is the dot target generator 5 at the optical center of the reflector 7 Is the vertical distance in the dot-site optical axis direction to the inner surface of the dot-site housing 10 in the direction in which is installed.)

)보다 작게 할 수는 없었다. In particular, in the conventional dot site, the vertical distance of the position of the dot target generator 5 in the dot sight optical axis C1 is less than D2 in order to prevent the light rays emitted from the dot target generator 5 from being exposed to the counterpart. The angle between the optical axis C2 of the reflector and the dotsite optical axis C1 of the reflecting mirror was not shortened.

Couldn't be smaller than

Therefore, the reflector with the inclination with respect to the dot-site optical axis has a larger amount of finite ray aberration than the reflector without the inclination, so that the parallax of the peripheral portion of the dot-site reflector is increased.

In addition, as shown in FIG. 1, in the conventional arrangement of the dot sight generation section, the light beam of the dot sight generation section is not visible at a very long distance in the direction of the visual axis of the dot sight of the dot sight so that the dot site observer can contact the external counterpart. Although it may not be detected, the other party that is located near the dot site optical axis, for example, at a close distance in the V2 direction, may observe the light beam emitted from the dot sight generator of the dot site, thereby completely exposing the dot site observer. There is a disadvantage that can not be blocked.

Patent Document 1. Registered Patent No. 0667472, Jung In (2007.01.10)

Accordingly, an object of the present invention is to solve such a conventional problem, and includes a first polarized light in which a light beam generated from a dot target generator by a pair of first and second polarized parts is provided in front of a reflector. The present invention provides a dot-site apparatus having a polarization means capable of preventing the observer from being detected by detecting the light beam by the dot-target generating unit on the other side and preventing the parallax of the reflecting mirror.

Also, in order to minimize the parallax of the reflector, even when the dot target generator is disposed on a window that is exposed to the front, the first polarizer and the second polarizer can be used without being detected by the other party. If the distance from the table generator is the same, a larger reflector can be used for the amount of parallax allowed by the existing dot site, and if the same size reflector is used, the distance from the reflector to the dot target generator can be shorter. Disclosed is a dot site apparatus having polarizing means.

In addition, when the light beam from the dot target generator is not dangerous to the other party, the first polarized light can be separated and removed from the front of the reflector, thereby sufficiently securing the amount of light incident from the outside as necessary. Disclosed is a dot site apparatus having polarizing means.

The above object is, according to the present invention, a reflecting mirror; and a first polarizing portion provided in front of the reflecting mirror; and a dot time generating unit for forming a dot virtual image by irradiating light to the reflecting mirror; And a second polarization part provided in front of the table generator, wherein the first polarization part and the second polarization part are arranged so that the light rays of the dot target generation part passing through the second polarization part are blocked by the first polarization part. It is achieved by a dot sight device with a polarizing means characterized by the above.

Here, the first polarizing portion is preferably assembled detachably in front of the reflector.

In addition, the first polarizing part and the second polarizing part may be made of linear polarizers having polarization directions orthogonal to each other, or rotating polarizers having opposite polarization directions.

The apparatus may further include a window disposed behind the reflector and fixed to the dot target generator.

In addition, it is preferable that the dot sight generator is provided in a region in which a reflecting mirror is projected in the optical axis direction of the dot sight on the window.

In addition, the window is preferably formed with a transparent electrode circuit line for supplying power to the dot target generator.

According to the present invention, since the light rays generated from the dot target generator by the pair of first polarizer and the second polarizer do not pass through the first polarizer provided in front of the reflector, the dot target is generated on the other side. The polarized light can reduce the parallax of the reflecting mirror because the light emitted from the part can be observed and the observer can be prevented from being detected, and the angle between the dot target and the dot sight optical axis of the dot target generating unit can be freely designed. A dot site apparatus with means is provided.

Also, in order to minimize the parallax of the reflector, even when the dot target generator is disposed on a window that is exposed to the front, the first polarizer and the second polarizer can be used without being detected by the other party. If the distance from the table generator is the same, a larger reflector can be used for the amount of parallax allowed by the existing dot site, and if the same size reflector is used, the distance from the reflector to the dot target generator can be shorter. A dot site apparatus with polarizing means is provided.

In addition, when the light beam from the dot target generator is not dangerous to the other party, the first polarized light can be separated and removed from the front of the reflector, thereby sufficiently securing the amount of light incident from the outside as necessary. A dot site apparatus with polarizing means is provided.

A housing 110 having one end portion facing the target and the other end facing the observer, a reflector 120 formed at one end of the barrel, and a first polarizing portion 130 provided in front of the reflector 120. ), A dot target generation unit 140 provided at the other end of the barrel, and a second polarization unit 150 provided in front of the dot target generation unit 140.

The housing 110 has a closed or open barrel formed therein and is installed in firearms such as guns, and the housing 110 is positioned between the housing 110 and the firearm in the up, down, left, and right directions. The fine ballistic control unit can be installed to finely adjust.

The reflector 120 is installed at one end of the barrel of the housing 110 to reflect the light beam provided from the dot target generator 140 toward the viewer and to transmit the image of the target to the observer. In order to aim the virtual image of the dot target reflected on the target to the target, the singlet reflector 120 or the 'dot-site sighting' No. 10-0667472 applied to a normal dot site. Doublet reflector 120 or the like as described may be applied.

The dot target generation unit 140 is a structure having a light emitting means and a light transmitting reticle which is located at the tip of the light emitting means and emits light emitted from the light emitting means to form a dot target, or a pixel such as an OLED, an LCD, an LCOS, or the like. It has a structure which can form a dot target by activation of. Here, the light transmitting reticle is made of a rotatable structure so that it is possible to select the type of the dot target according to the type or distance of the target, the desired position when the dot target generator 140 is made of OLED, LCD, LCOS, etc. It is also possible to fine tune the dot shape or the dot position by activating the pixel.

The first polarizer 130 and the second polarizer 150 are installed in front of the reflector 120 and the dot target generator 140, respectively, the first polarizer 130 and the second polarized light In the case where the part 150 is made of linear polarizers, the polarization directions of the parts 150 are orthogonal to each other, and in the case of the polarizers, the polarization directions of the parts 150 are opposite to each other.

In general, since the rotating polarizer is composed of a combination of linear polarizer and quarter-wave plate, the linear polarizer and the linear polarizer of the rotating polarizer face each other, but the polarization direction of the linear polarizer and the rotating polarizer By making the polarization directions of the linear polarizers perpendicular to each other, it is possible to prevent the light rays of the dot target generator 140 from passing outside. In addition, the pair of rotary polarizers may face each other with the linear polarizers, but the polarization directions may be perpendicular to each other so that the light rays of the dot target generator 140 may not pass to the outside.

Therefore, in the present exemplary embodiment, the first polarizing unit 130 and the second polarizing unit 150 are configured as a pair of linear polarizers in which the polarization directions are perpendicular to each other, or a pair of rotary polarizers in which the polarization directions are opposite to each other. For example, the present invention is not limited thereto, and the light beam of the dot target generator 140 may not pass through the combination of at least two polarizers.

The operation of the first embodiment of the dot sight device with polarizing means described above will now be described.

As shown in FIG. 6, in the dot sight aiming device having the polarizing means of the present invention, the first polarizing portion 130 and the reflecting mirror 120 are sequentially installed from one end to the one end located in front of the barrel of the housing 110. The other end portion is provided with a dot target generator 140 toward the reflector 120, and the second polarizer 150 is installed in front of the dot target generator 140.

The dot target generation unit 140 has a structure in which the dot target generation unit 140 can form a dot target by activating pixels such as OLED, LCD, LCOS, or the leading end of the light emitting means and the light emitting means. The light emitting device may be configured to have a light transmitting reticle which is positioned at and emits light emitted from the light emitting means to form a dot target. The second polarization unit 150 is disposed in front of the dot target generation unit 140 as described above.

As described above, the housing 110 in which the dot sight generator 140 and the reflector 120 are installed is fixed to a gun (not shown) such as a mount for a heavy machine gun, and zero is adjusted through a ballistic controller. The external object is identified through the polarizer 130 and the reflector 120. At this time, the light beam irradiated from the dot target generator 140 is reflected on the reflector 120 and is incident to the observer's eye, and the dot target reflected by the reflector 120 is recognized by the observer while forming a dot virtual image. .

When the first polarizer 130 and the second polarizer 150 are linear polarizers, light beams emitted from the dot target generator 140 pass through the second polarizer 150 in a specific direction. The light is converted into a ray of linearly polarized light and then reflected by the reflector 120 and observed as a dot virtual image in the observer's eye. However, the light beam irradiated from the dot table passing through the reflector 120 is blocked without going outside because the polarization direction is orthogonal to the polarization direction of the light beam that may pass through the first polarization unit 130.

In addition, even when the first polarization unit 130 and the second polarization unit 150 are circular polarizers, the light rays radiated from the dot target generation unit 140 pass through the second polarization unit 150. The light is turned into a ray of rotation polarization with a particular direction of rotation (eg, right rotation) and then reflected by the reflector 120 to be observed as a dot virtual image in the observer's eye. However, the light beam irradiated from the dot table passing through the reflector 120 is moved to the outside because the direction of rotation polarization is opposite to the polarization direction (for example, left rotation) of the light beam that can pass through the first polarization unit 130. It can't go and it's blocked.

Therefore, when the first polarization unit 130 and the second polarization unit 150 are installed as described above, the light rays generated from the dot target generation unit 140 are disposed in front of the reflector 120. Since it does not pass 130, the light beam by the dot time is observed on the other side, and the observer is prevented from being detected.

Here, the first polarizing unit 130 and the second polarizing unit 150 may be configured to coat or have a polarizing film attached to a glass plate or the like, or to insert a polarizing film between the two glass plates or . It can be configured by various methods such as a thick polarizing film.

Next, a dot site apparatus with polarizing means according to a second embodiment of the present invention will be described.

FIG. 7 is a cross-sectional view showing other embodiments of a dot site apparatus with polarizing means of the present invention, and FIG. 8 is a front view showing the window side of FIG.

As shown in FIG. 7, another embodiment of the dot sight device with polarizing means according to the present invention is configured as a closed dot sight while the shape of the housing 110 is different from that of the open housing 110 of the above-described embodiment. The window 160 is disposed at a portion facing the eye, the dot target generator 140 is fixed to the window 160, and the second polarizer 150 is disposed in front of the dot target generator 140. It differs from the above-mentioned embodiment in terms of installation.

7 (a) to 7 (c) show that the positions of the dot target generator 140 are different from each other, and (a) shows the dot target generator 140 at the same position as the first embodiment. (B) is a dot dot generation unit 140 is located on the window 160 to approach the dot site optical axis than FIG. The light rays emitted from the table can be seen by the other party located in front of the dot site, (c) shows the state in which the dot target generator 140 is installed at the position where the optical axis of the dot site passes. The parallax of the reflector 120 becomes small in order (a), (b), (c).

That is, as shown in FIGS. 7B and 7C, the dot sight generating unit 140 is disposed on the window 160 to approach the position where the dot sight optical axis passes, or the dot sight optical axis passes. Even in the case of reducing the occurrence of parallax of the reflecting mirror 120 by placing at a position to be, in the case of a conventional dot site, there is a disadvantage in that the light emitted from the dot target is visible to the other party located in front of the dot site, but in the present invention, the second The light beam of the dot target generator 140 passing through the polarizer 150 is blocked by the first polarizer 130 disposed in front of the reflector 120 and irradiated from the dot target generator 140 from the outside. You will not be able to observe the light rays, so you can use them without being detected by your opponent.

Therefore, the dot target generator 140 of the dot sight device with the polarizing means of the present invention may be provided at any position in the region where the reflector 120 is projected in the dot sight optical axis direction on the window 160. That provides the benefits.

In addition, the present invention is not only provided with the dot sight generating unit at the same position as the conventional dot sight, but also with the dot sight generating unit located close to the dot sight optical axis on the window 160 as shown in FIGS. 7B and 7C. Since the light rays of the dot target generator 140 are blocked by the first polarizer 130 and the second polarizer 150, the distance from the reflector 120 to the dot target generator 140 is the same. When the amount of parallax allowed by the existing dot sight is allowed, a larger reflector 120 may be used, and if the same size reflector 120 is used, the reflector 120 to the dot target generator 140 may be used. It is possible to use a shorter distance.

That is, in the dot-site device having the polarizing means of the present invention, since the light rays emitted from the dot sight generator 140 are not exposed to the counterpart, the angle between the optical axis of the reflector and the dot-site optical axis is not limited. Therefore, this angle is set to 0 degrees as shown in FIG. Among the dot sites having the same D1 and D2, the dot site with the least parallax of the reflecting mirror can be configured.

8 illustrates a window 160 to which the dot target generator 140 is attached and fixed. The transparent electrode circuit line 170 (generally, the power supply line) of the dot target generator 140 is a window ( When the dot target generator 140 is connected to the edge of the window 160 that does not obstruct the view by using a transparent electrode such as Indium-Tin Oxide (ITO) attached to the 160, the dot In the rear window region except for the target generator 140, a view for viewing an external target point may be secured.

In addition, although not shown in the drawings, the above-described first polarization unit 130 is coupled to the housing 110 in a detachable structure in front of the reflector 120 so that the light beams from the dot target generator 140 are counterparted. It may be attached to the front of the reflector 120 in order to avoid exposure to the light, and when the light beam from the dot target generator 140 is not dangerous to the other party, the second polarized portion in the field of view of the reflector 120 By separating and removing the 150, it may be possible to have a structure that can further secure the amount of light incident from the outside as needed.

In addition, as shown in another embodiment of FIG. 9, the above-described first polarization unit 130 is mounted on a cap-shaped cap housing 111 to have an uneven shape on the housing 110 in front of the reflector 120. To be coupled to the removable structure using the groove of the dot target generator 140 may be attached to the front of the reflector 120 to avoid exposure to the other side, the dot target generator 140 When the light emitted from the other side is not exposed to the counterpart, the first polarizer 130 may be separated and removed from the front view of the reflector 120, thereby additionally securing the amount of light incident from the outside. It may be possible to have a structure that is. Of course, the cap housing 111 on which the first polarizing unit 130 is mounted may be attached to or detached from the housing 110 in various forms.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
