Description

COMPLEX OPTICAL SIGHTING DEVICE}

The present invention relates to a complex optical aiming device, and more specifically, provides an optical scope module capable of precise aiming at a long distance, a thermal imaging module capable of aiming in a dark environment, and a dot sight module capable of rapid aiming at a short distance in one housing, It relates to a complex optical aiming device that can facilitate switching between each mode.

Typically, a sight can be coupled to one side of the firearm to accurately aim at an external target. However, in the case of firearms, especially rifles, aiming is achieved by aligning the sight lines of the sights and sights. Speed, which indicates how quickly the aim is achieved and an aimed shot can be made, and accuracy, which indicates whether the aimed shot is accurately aimed at the target. This is very important.

However, even small vibrations or tremors make it difficult to align the aiming line, and there are problems with quick aiming required in close quarters or urgent situations.

In other words, the point-and-shoot method requires complex processes and time such as target capture and confirmation, line alignment, and aiming, and the sights and sights themselves are very small, so not only do they react sensitively to small vibrations in accurately aligning them, but they also require excessive alignment of the line of sight. If you pay attention, your gaze will be focused on the sights themselves rather than on the target or the situation ahead, narrowing your field of view.

An optical scope was proposed to improve accuracy while solving the inconvenience of aligning the aiming line.

Optical scopes use an optical system with magnification consisting of an objective lens and an alternative lens reticle to magnify the target, so it has excellent target identification ability and allows precise aiming through the reticle inside the scope. Make it possible.

This type of optical scope requires an upright optical unit that changes the inverted image into an upright image, and it is largely divided into prism type and relay lens type. Figure 1 is a structural diagram of a prism-type optical scope, and Figure 2 is a structural diagram of a relay lens-type optical scope.

First, referring to FIG. 1, the prism-type optical scope 10 is composed of an objective lens 11, a prism optical system 12, a reticle 13, and an eyepiece 14. In Figure 1, the objective lens 11 and the eyepiece 14 are each composed of one lens, but in reality, they may be composed of multiple lenses to eliminate aberrations, etc.

The principle of the telescope is that when the image of an external object by the objective lens 11 is imaged at the position of the reticle 13, the image of the external object and the reticle 13 are simultaneously viewed and enlarged by the eyepiece 14. At this time, if the image of the objective lens 11 is formed on the reticle 13 as is, the image appears upside down, so it is made to look upside down again so that the image seen through the eyepiece 14 can be straightened by using the objective lens 11 and the reticle. (13) The prism optical system (12) is an upright optical unit that plays the role of changing the inverted image into an upright image.

Next, referring to FIG. 2, the optical scope 10' adopting the relay lens method, which is another method of the upright optical unit that plays the role of changing the inverted image to the upright image, includes an objective lens 11 and a field lens 15. , it consists of a reticle (13), a relay lens (16), and an eyepiece (14). In Figure 2, the objective lens 11, field lens 15, and eyepiece lens 14 are each composed of one lens, but in reality, they may be composed of multiple lenses to eliminate aberrations, etc.

When the image of an external object by the objective lens 11 is formed at the position of the reticle 13, the relay lens 16 re-images the image of the external object and the target of the reticle 13 in front of the eyepiece 14 at the same time. The principle of a relay lens telescope is to change an inverted image into an upright image and magnify it using the eyepiece 14. At this time, if the image of the objective lens 11 forms an image on the reticle 13 as is, the image is inverted and appears upside down. This is re-imaged by the relay lens 16 to make it appear upside down again, so that the image in front of the eyepiece 14 The image is formed as an erect image, and the eyepiece 14 magnifies this image.

Here, the field lens 15 present before and after the relay lens 16 serves to collect the light flux incident on the relay lens 16.

The optical scope has the advantage of being able to zoom and aim at a target, but in order to match the target of the reticle 13 (sight line alignment), the gaze line of the observer's eye passes through the target of the reticle 13 and the target. Therefore, in order to aim, the observer's eye position must be moved so that the eye's line of sight passes through the center of the observation window within the scope. Therefore, in order to shoot accurately, the observer must always place his/her eyes at the center of the observation window when shooting. If a target is seen around the observation window, the target is placed at the center of the observation window again and the barrel is adjusted so that the observer's eyes are also at the center of the observation window. need to adjust This action impedes the speed of shooting because it delays the shooting time.

Dot site was proposed to solve this problem.

The dot sight is characterized by simple and quick aiming, and has the advantage of being very useful in urgent situations or close range that require a quick response.

In other words, the dot sight requires almost no time to align the aiming line, and the aiming itself can be done by quickly moving the virtual image by the reflector of the dot reticle of the dot generator to the target. Unlike the optical scope, the dot sight Since there is no need to move and view the virtual image caused by the reflector of the dot target at the dot generator in the center of the observation window, it has the advantage of minimizing not only the time required for aiming but also the disruption to peripheral vision and situation confirmation due to aiming.

Figure 3 is a structural diagram of a general dot site device. Referring to FIG. 3, the above-described dot sight device 20 includes an internal barrel alignment control terminal 22 located at the top of the sight housing 21 of a cylindrical structure, and a rifle sight located at the bottom of the housing 21. A fixed grill (23) detachably connected to the top of the bundle (not shown) in a rail manner, a protective window (24) located inside the housing (21), and a dot located at a certain portion on the inner side of the barrel inside the housing (21). It may be configured to include a target generator 25 and a reflector 26 that has a specific curvature and is located behind the protective window 24 inside the housing 21.

The user (observer) can facilitate aiming by shooting when the virtual image created by the reflector of the dot target generator of the dot target generator matches the target.

On the other hand, since the above long-distance optical scope and short-distance dot sight can observe the target only when the surrounding environment is bright, in a dark environment where the target cannot be observed by visible light, infrared wavelength light generated from the target is used. A separate thermal imaging sight that can observe the target using is required.

This thermal imaging collimator includes an infrared imaging objective lens that forms an infrared image, an infrared detection element that detects infrared rays, a display unit that provides the thermal image signal detected by the infrared detection element as an image for the user to view, and a display unit. It may consist of an eyepiece that magnifies the image output from the unit.

However, if the user carries each of the optical scope, dot sight, and thermal imaging sight as described above, selects one depending on the surrounding situation, mounts it on the firearm, and then aims at the target, not only is it impossible to respond quickly, but the user also has to carry the sight. As the equipment required increases, movement becomes inconvenient.

In addition, when attaching an optical scope, dot sight, and thermal imaging sight to the mounting rail provided on the gun, the volume and weight of the gun increase, making it less portable, and using aiming devices attached at different positions depending on the surrounding situation. When aiming at a target, it is difficult to respond quickly.

As it is in close contact with the other side of 153b), the second moving position of the moving member 154 is guided, so that the display unit 143 can be positioned at an accurate position in front of the eyepiece 120.

When the display unit 143 is disposed in front of the eyepiece 120 as described above, infrared rays incident from the target in front pass through the thermal imaging objective lens 141 and are provided to the infrared detection element 142 to produce a thermal image. A signal is generated, and the thermal image signal is displayed through the display unit 143 electrically connected to the infrared detection element 142, so that an image is formed in the user's eyes through the eyepiece 120. In other words, the user can observe the image of the target using infrared rays in a dark environment, and through this, can aim at the target.

Figure 14 shows a state in which a user aims at a target ahead through the dot site module 160.

The light incident from the target in front passes through the reflector 161 and the beam splitter 163 of the dot site module 160 disposed in the third through hole 113 of the housing 110 and forms an image in the user's eyes. The dot mark provided from the dot mark generator 162 disposed on the bottom of the beam splitter 163 is reflected from the beam splitter 163 toward the reflector 161, and is reflected back from the reflector 161 and then returned to the beam. It passes through the splitter 163 and is presented to the user's eyes.

Among the accompanying drawings, Figure 16 is a schematic configuration diagram showing a switching unit of a complex optical aiming device according to a third embodiment of the present invention.

As shown in FIG. 16, according to the third embodiment of the present invention, the reticle 133 of the optical scope module 130 is disposed in front of the eyepiece 120, and the display unit of the thermal imaging module 140 (143) is disposed in a position away from the optical path between the reticle 133 and the eyepiece 120, and the transition portion 150" is disposed at an angle in the area between the reticle 133 and the eyepiece 120. It includes a moving member (154") disposed to be movable, and the surface of the moving member (154") facing the display unit 143 is capable of reflecting light provided from the display unit 143. A reflective surface can be formed.

Specifically, when the moving member 154" is rotated to the first moving position as shown in (a) of FIG. 16, the moving member 154" is positioned between the reticle 133 and the eyepiece 120. Since the light rays from the reticle 133 deviate from the beam are provided toward the eyepiece 120, the user can observe the image of an external object imaged on the reticle 133.

In addition, when the moving member 154" is rotated to the second moving position as shown in (b) of FIG. 16, the moving member 154" moves along the optical path between the reticle 133 and the eyepiece 120. It is inclined to block the light from the reticle 133 and at the same time reflects the light provided from the display unit 143 toward the eyepiece 120, so that the user receives heat output through the display unit 143. The image signal can be observed.

Meanwhile, in this embodiment, it is explained as an example that the moving member 154" moves to the first and second moving positions while rotating, but the moving member 154" moves to the first moving position and the second moving position in (b) of FIG. 16. It would also be possible to configure it to move to another first movement position while sliding in the Z-axis direction shown in (b) of FIG. 16.
