Description

Technical Field

[0001] This utility model belongs to the field of military optical instrument technology, and in particular relates to a three-light fusion gun sight optical system based on dynamic focusing of a wedge mirror. Background Technology

[0002] The gun aiming scope can be installed in the barrel of guns of various calibers. By aligning the gun's base sight axis with the gun's main sight axis, and the aiming axis with the firing line axis, the aiming scope ensures that the operator can quickly and accurately aim at the target and fire during combat. Guns corrected with the gun aiming scope have better sight accuracy and a higher first-round hit probability, effectively improving combat effectiveness.

[0003] The existing technology has the following problems: 1. Single spectrum dependence: Traditional gun calibration scopes rely only on visible light and fail at night or in foggy weather; 2. Insufficient calibration accuracy: Traditional visible light gun calibration has a single optical system and lacks laser assistance, making it difficult to achieve close-range dynamic calibration; 3. Poor environmental adaptability: It is difficult to select sites and has poor versatility. It cannot perform real-time gun calibration in extreme weather or poor terrain.

[0004] Therefore, there is an urgent need for a new technical solution to address this problem. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a three-light fusion gun-calibrating scope optical system based on dynamic focusing of a wedge mirror, so as to solve the problems of poor environmental adaptability and low calibration efficiency of traditional gun-calibrating scopes in the prior art.

[0006] The technical solution adopted by this utility model is to provide a three-light fusion gun-calibrating optical system based on dynamic focusing of a wedge mirror, including a visible light objective lens, a first wedge mirror, a second wedge mirror, a laser collimation module, a low-light mechanism, a first right-angle prism, a second right-angle prism, a reticle, and an eyepiece. The visible light objective lens, the second right-angle prism, the first right-angle prism, and the low-light mechanism are arranged sequentially along the optical axis. The light beam is imaged onto the electronic reticle built into the low-light mechanism after being split by the first right-angle prism. The low-light mechanism is connected to a display, which is used for low-light gun calibration.

[0007] Among them, right-angle prism one and right-angle prism two are two identical right-angle prisms with a beam-splitting film coated along the inclined surface and maintaining an air gap of 0.1 mm. The visible light objective lens is parallel to the incident surface of right-angle prism two, and the reticle is parallel to the exit surface of right-angle prism two. After the beam is split by right-angle prism two, it is rotated 90 degrees and imaged on the plane of the reticle. It is then observed by the eyepiece through the reticle. The eyepiece is used for visible light gun calibration.

[0008] The laser collimation module is parallel to the optical axis, and a wedge-shaped mirror group is provided at the front end of the laser collimation module. The wedge-shaped mirror group can rotate along the laser optical axis.

[0009] The wedge mirror assembly consists of two identical wedge mirrors, wedge mirror one and wedge mirror two, which are attached together along an inclined plane. By rotating wedge mirror one or wedge mirror two, the laser spot is focused onto the target cloth for laser gun calibration.

[0010] Through the above design scheme, this utility model can bring the following beneficial effects:

[0011] 1. Visible light (400-700nm), low light (850nm), and laser (635nm±5nm) are transmitted synchronously through objective lens, beam splitter, and wedge lens group to achieve coaxial fusion of three beams.

[0012] 2. The optical path is adjusted in real time by rotating the double wedge mirrors so that the electronic reticle, laser spot and optical reticle coincide at the target distance.

[0013] 3. The low-light camera module supports 0.001Lux imaging, and the laser penetration attenuation rate in fog and haze is <5% / km, making it adaptable to all weather conditions.

[0014] 4. Applicable to various complex terrains, weather conditions, day and night, and long (1200 meters) and short (40 meters) distances, as well as the needs of various types of artillery calibration. It solves the problems of difficult calibration under severe weather and low light conditions and limited calibration sites, and realizes rapid and accurate calibration in all weather, all terrains and all time domains, greatly improving the adaptability of the product.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-2 As shown, the present invention discloses a three-light fusion gun-calibrating optical system based on dynamic focusing of a wedge mirror, comprising a visible light objective lens 1, a wedge mirror 1 2, a wedge mirror 2 3, a laser collimation module 4, a low-light mechanism 5, a right-angle prism 1 6, a right-angle prism 2 7, a reticle 8, and an eyepiece 9. The visible light objective lens 1, the right-angle prism 2 7, the right-angle prism 1 6, and the low-light mechanism 5 are arranged sequentially along the optical axis. The light beam is imaged onto the electronic reticle built into the low-light mechanism 5 after being split by the right-angle prism 1 6. The low-light mechanism 5 is connected to a display, which is used for low-light gun calibration.

[0023] Among them, right-angle prism 1 (6) and right-angle prism 2 (7) are two identical right-angle prisms with a beam-splitting film coated along the inclined surface and maintaining an air gap of 0.1 mm. The visible light objective lens 1 is parallel to the incident surface of right-angle prism 2 (7), and the reticle 8 is parallel to the exit surface of right-angle prism 2 (7). After the beam is split by right-angle prism 2 (7), it is rotated 90 degrees and imaged on plane A of reticle 8. The beam is then observed by eyepiece 9 through reticle 8. Eyepiece 9 is used for visible light gun calibration.

[0024] The laser collimation module 4 is parallel to the optical axis. The front end of the laser collimation module 4 is equipped with a wedge-shaped mirror group. The wedge-shaped mirror group can rotate along the laser optical axis. The wedge-shaped mirror group consists of two identical wedge-shaped mirrors, 2 and 3, which are attached to the inclined plane. By rotating wedge-shaped mirror 2 or wedge-shaped mirror 3, the laser spot is focused onto the target cloth for laser gun calibration.

[0025] Set up close-range artillery target mats at 40m or long-range artillery target mats at 1200m, such as... Figures 3-4 As shown, there is one crosshair on the long-range artillery target cloth, and two crosshairs on the short-range artillery target cloth.

[0026] Example 1:

[0027] During the day, in good weather, a 1200m long-range target cloth was used for artillery calibration. The visible light mode was selected, and the artillery calibration scope was installed in the gun barrel. At this time, the optical axis of the artillery calibration scope was coaxial with the gun barrel. When observing through the eyepiece 9, the magnified crosshairs of the artillery calibration target cloth and the reticle 8 could be seen clearly at the same time. By moving the gun barrel, the reticle 8 was aligned with the crosshairs of the artillery calibration target cloth. Then, the base aiming line was adjusted to be aligned with the crosshairs of the artillery calibration target cloth, thus completing the base aiming axis correction and the artillery calibration at 1200m was completed.

[0028] Example 2:

[0029] During the daytime, in good weather, a 1200m long-range target cloth was used for calibration. The low-light mode was selected, and the calibration scope was installed in the gun barrel. At this time, the optical axis of the calibration scope was coaxial with the gun barrel. When observing through the monitor, the magnified crosshairs of the calibration target cloth and the reticle of the electronic reticle could be seen at the same time. By moving the gun barrel, the electronic reticle was made to coincide with the crosshairs of the calibration target cloth. Then, the base aiming line was adjusted to coincide with the crosshairs of the calibration target cloth, thus completing the base aiming axis calibration and completing the calibration of the gun at 1200m.

[0030] Example 3:

[0031] During the daytime, in adverse weather conditions such as fog, light rain, or light snow, use a 40m close-range target cloth for gun calibration. Select visible light mode and install the calibration scope into the gun barrel. At this time, the optical axis of the calibration scope is coaxial with the gun barrel. When observing through eyepiece 9, you can simultaneously see the magnified crosshairs on the calibration target cloth and the reticle 8. By moving the gun barrel until the reticle aligns with one crosshair on the calibration target cloth, and then adjusting the base aiming line to align with the other crosshair on the calibration target cloth, the base aiming axis calibration is completed, which is equivalent to completing the calibration of the gun at 1200m. Figure 5 As shown.

[0032] Example 4:

[0033] During the daytime, in adverse weather conditions such as fog, light rain, or light snow, use a 40m close-range target cloth for artillery calibration, select low-light mode, and install the artillery calibrator into the gun barrel. At this time, the optical axis of the artillery calibrator is coaxial with the gun barrel. When observing through the monitor, you can simultaneously see the magnified crosshairs on the target cloth and the reticle of the electronic reticle. By moving the gun barrel to make the electronic reticle coincide with one of the crosshairs on the target cloth, and then adjusting the base aiming line to coincide with the other crosshair on the target cloth, the base aiming axis correction is completed, which is equivalent to completing the artillery calibration at 1200m.

[0034] Example 5:

[0035] During the daytime, in adverse weather conditions such as fog, light rain, or light snow, use a 40m close-range gun calibration target cloth, select laser mode, and install the calibration scope into the gun barrel. At this time, the optical axis of the calibration scope is coaxial with the gun barrel. Turn on the laser collimation module 4, and move the gun barrel to focus the laser spot on a crosshair on the calibration target cloth. Then adjust the base aiming line to coincide with another crosshair on the calibration target cloth, thus completing the base aiming axis correction, which is equivalent to completing the correction of the artillery at 1200m.

[0036] Example 6:

[0037] At night, using a 40m close-range target cloth, select low-light mode and install the aiming scope into the gun barrel. At this time, the optical axis of the aiming scope is coaxial with the gun barrel. When observing through the monitor, you can simultaneously see the magnified crosshairs on the aiming target cloth and the reticle of the electronic reticle. By moving the gun barrel to make the electronic reticle coincide with one of the crosshairs on the aiming target cloth, and then adjusting the base aiming line to coincide with the other crosshair on the aiming target cloth, the base aiming axis correction is completed, which is equivalent to completing the correction of the artillery at 1200m.

[0038] Example 7:

[0039] At night, using a 40m close-range target cloth, select laser mode and install the aiming sight into the gun barrel. At this time, the optical axis of the aiming sight is coaxial with the gun barrel. Turn on the laser collimation module 4, move the gun barrel to focus the laser spot on a crosshair on the target cloth, and then adjust the base aiming line to coincide with another crosshair on the target cloth. This completes the base aiming axis correction, which is equivalent to completing the correction of the artillery at 1200m.

[0040] This invention can be applied to rapid and accurate artillery calibration for all types of artillery in all weather, all terrain, and all time domains.

[0041] The implementation of this utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this utility model shall be considered equivalent substitutions and shall be included within the protection scope of this utility model.
