Description

Dot sight combined external target observation device

The present invention relates to an external target observing apparatus for both dot sites, and more particularly, in the process of superimposing and observing an image of a dot target formed by a coating surface of a reflector on a target, the coating surface of the reflecting mirror is not formed. The present invention relates to a dot-site combined external target observing device capable of preventing some reflected rays from forming on the viewer's retina.

The characteristics of a rifle or heavy machine gun depend on whether you can aim quickly and you are aiming precisely at the target. In general, aiming a rifle or heavy machine gun is achieved by aligning the line of sight with the scale. Aiming by alignment of the aiming line of the scale located at the end of the barrel and the scale located above the gun body enables accurate shooting according to the skill of the user using the firearm.

However, aiming at the scale and the scale alone makes it difficult to align the line of sight even with small vibrations and tremors, and it is also difficult to aim quickly 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 alignment of the line of sight results in a narrower field of view for dealing with fire or emergencies due to focusing attention on the scale and the scale itself rather than on the target or forward situation.

Therefore, in order to cope with such difficulty in line alignment and to increase the accuracy of aiming, a sighting device equipped with a telephoto lens has been proposed. However, in the case of an optical sight equipped with a telephoto lens, when the magnification of the telephoto lens is increased, it is similarly sensitive to small vibrations, and therefore, the rapid aiming still has many difficulties.

As a result, in order to solve these problems, a dot-site apparatus using a magnification-free or low-magnification lens for an optical sight and eliminating a complicated aiming line and simply using a aiming point has been proposed.

Optical magnification (or low magnification) dot sight aiming devices are simple and quick to aim, and are very useful in emergency situations or at close range. Specifically, it is possible to reduce the time required to align the conventional aiming line, and since the aiming itself is enough to just place the virtual image of the dot target on the target, it is possible to afford a view. In the end, you can aim quickly and accurately, and you can also secure the surrounding vision needed for context determination.

As shown in FIG. 1, the optical dot sight has an inner barrel aligning control terminal 3 positioned on an upper collimator housing 2 having a cylindrical structure, and detachably connected to a rifle scale bundle by a rail on a lower portion thereof. The fixed grill 11 is configured to include a protective window 9 at the front end of the housing, a light emitting device LED 5 for generating a light source at a predetermined position in the upper part of the housing 2, and a specific bending rate. It comprises a reflector (7) located behind the protective window (9).

The reflector 7 sees the eyes of the user (hereinafter, the observer) at the tip of the dot sight device 1, and reflects the light spot of the LED 5 having a light beam of about 650 nm to the rear end. The observer can facilitate aiming by shooting when the light spot of the LED matches the target.

However, in the conventional dot sight aiming device, when observing a CCD image of an external target or looking at an infrared image at night or on a foggy day of an external target, the observation is stopped by a dot sight and the CCD image or an infrared image is displayed. There was a discomfort to reposition the eyes to see the equipment. This behavior can lead to missed targets for observation tracking due to misalignment of the optical axis with respect to the targets of the two instruments and shift of eye position for the observation of the two instruments.

Therefore, an object of the present invention is to solve such a conventional problem, in the process of observing the dot target image formed by the coating surface of the reflector superimposed on the target, in the surface where the coating surface of the reflector is not formed An object of the present invention is to provide a dot-site combined external target observing device capable of preventing some reflected rays from forming on an observer's retina.

In addition, while maintaining the attitude that the observer observes the target through the barrel, the observer can directly aim at the target while observing the target using the optical system, or can aim at the dot target while observing the target image image. The present invention provides an external target observing apparatus for a dot site.

Reflector formed with a second coating layer for transmitting the light beam; And a light source generator disposed on one side of the optical unit to provide a light beam having a predetermined shape to the optical unit, wherein the radius of curvature of the first curved surface is partially reflected from the first curved surface by diverging from the light source generating unit. The light beam is set to travel toward divergent light toward the observer, and the radius of curvature of the second surface is set to diverge from the light source generator so that the light reflected on the second curved surface travels in parallel to the observer. It is achieved by a dot-site combined external target observing apparatus.

Here, the reflector is preferably made of a singlelet lens.

Further, it is preferable that the curvature radius R1 of the first curved surface and the curvature radius R2 of the second curved surface are set so as to satisfy the relationship of R1 <R2.

The apparatus may further include an observation camera connected to the display unit in a wired or wireless manner so as to provide an image image of the target to the display unit. The optical axis of the observation camera may be set to be parallel to the optical path of the barrel.

A dot-site combined external target observing apparatus is provided.

That is, when it is difficult to observe the front target because the front vision is poor, such as in a dark environment, the front target may be observed by providing a CCD image, a thermal image, and an IR image through the display unit 160. Since the dot target image is provided to the retina of the target, the target of the image information provided through the display unit 160 can be easily aimed using the dot target.

In particular, as one light source 110 is disposed within the light source generator 140 providing a dot mark and the display unit 160 providing an image image of the target, the observer directly views the target.
