Description
Technical Field
The invention belongs to the technical field of laser simulation emission, and particularly relates to an automatic rifle simulation shooting light source system based on double laser coupling.
Background
The application relates to a double-laser-spot coupled automatic rifle simulated shooting light source system. In the traditional shooting excitation process of the laser simulation automatic rifle, a visible or invisible laser light source is used as a laser emission light source, and when a trigger of the automatic rifle is pulled, the laser simulation excitation system can trigger the laser light source to emit. However, the laser light source is a gaussian light beam, and is characterized in that with the increase of the laser transmission distance, the laser spot is gradually enlarged according to the basic rule of the divergence angle, so that the receiving area of the laser spot received by the laser target receiving system is gradually enlarged as the distance is increased. The hitting precision of the simulated shooting of the laser simulated automatic rifle is obviously reduced when the laser is close to the target receiving point; when the laser is far away from the target receiving point, the hit probability is obviously increased and even exceeds the effective hit probability of actual shooting. The basic common knowledge that a bullet hits a target is violated, so that the laser simulated shooting hit probability is seriously inconsistent with the live-fire shooting hit probability, and the improvement of the shooting result and the shooting training level of a shooter is influenced.
Disclosure of Invention
The invention aims to solve the problems and provides an automatic rifle simulated shooting light source system based on double laser coupling, which effectively solves the problem that the hit precision completely deviates from the ball firing hit result in simulated shooting; after double-light debugging, the laser can be directly used as a standard laser emission light source in an automatic rifle simulated shooting terminal, so that the laser driving and modulating modes are completely consistent.
In order to achieve the purpose, the invention provides the following technical scheme:
a double-laser-coupling-based automatic rifle simulated shooting light source system comprises a structural main body and is characterized in that the structural main body is of an inverted L-shaped structure, a first laser module is arranged at one end of the L-shaped structure, a second laser module is arranged at the other end of the L-shaped structure, a beam combiner is arranged at the turning end of the inverted L-shaped structure of the structural main body, the first laser module penetrates through the beam combiner to emit a straight first laser beam, and the second laser module refracts through the beam combiner to emit a second laser beam; the side wall of the structure main body close to the beam combiner is connected with an angle adjusting joint. The first laser beam has a larger divergence angle and is used for enlarging light spots and generating higher simulated shooting hit probability; the second laser beam has a small divergence angle for laser aiming at long distance shots.
Furthermore, the angle adjusting joint is used for adjusting the angles of the first laser beam and the second laser beam which pass through the beam combining mirror, so that the first laser beam and the second laser beam are coupled to form laser output with a uniform direction.
Furthermore, the beam combining mirrors are one group or two groups.
Further, the beam combining mirror is a beam combining mirror sheet or a beam combining prism.
Further, the angle adjusting joint is connected with the structure main body through threads.
Further, the angle adjusting joint is a spherical omnidirectional adjusting joint.
Compared with the prior art, the invention has the beneficial effects that:
in the double-optical coupling system, the light spot with larger beam diameter is rapidly enlarged due to the transmission along with the distance, the laser power density is rapidly reduced, the effective shooting distance is rapidly shortened, and the light spot is larger when the laser module with large light spot is in a close range, so that the shooting hit probability of the simulated automatic rifle is higher, and the shooting hit probability is consistent with the actual effect of higher precision of close-range live ammunition shooting;
in the double-optical coupling system, the light spot with smaller light beam diameter is transmitted along with the distance, the light spot is still smaller at the original distance, the laser power density keeps long distance, the effective shooting distance is obviously lengthened, the light spot is not large when the laser module with small light spot is in long distance, the shooting hit probability of the simulated automatic rifle is lower, and the energy transmission of the laser with large light spot can not reach the long distance section, so the simulated shooting precision is consistent with the actual effect of higher close-distance live ammunition shooting precision;
the invention effectively solves the problem of incorrect result that the hit precision completely deviates from the hit result of the live ammunition shooting in the simulation shooting; after double-light debugging, the laser can be directly used as a standard laser emission light source in an automatic rifle simulated shooting terminal, and the laser driving and modulation modes are completely consistent; therefore, the system is of an integral structure, and can be used as a single laser light source for adjustment in the laser adjustment process of the system, thereby effectively saving the adjustment time and improving the adjustment speed.

Detailed Description
In order to make the technical solutions of the present invention better understood and implemented by those skilled in the art, the present invention is further described with reference to the following specific examples, which are provided for illustration only and are not intended to limit the present invention.
As shown in fig. 1, an automatic rifle simulated shooting light source system based on double laser coupling includes a first laser module 1, a second laser module 2, a structural main body 3, a beam combining mirror 4, and an angle adjusting joint 5, wherein the structural main body 3 is an inverted L-shaped structure, one end of the L-shaped structure is provided with the first laser module 1, the other end is provided with the second laser module 2, the turning end of the inverted L-shaped structure of the structural main body 3 is provided with the beam combining mirror 4, the first laser module 1 passes through the beam combining mirror 4 to emit a straight first laser beam 11, and the second laser module 2 refracts and emits a second laser beam 21 through the beam combining mirror 4; the side wall of the structure body 3 close to the beam combiner 4 is connected with an angle adjusting joint 5 through threads. The angle adjusting joint 5 is used for adjusting the angles of the first laser beam 11 and the second laser beam 21 passing through the beam combining mirror 4, so that the first laser beam 11 and the second laser beam 21 are coupled to form laser output with a uniform direction. Preferably, the beam combining mirror 4 is a beam combining mirror sheet or a beam combining prism.
In the double-optical coupling system, the light spot with larger beam diameter is rapidly enlarged due to the transmission along with the distance, the laser power density is rapidly reduced, the effective shooting distance is rapidly shortened, and the light spot of the first laser module 1 with large light spot is larger at a close distance S1, so that the shooting hit probability of the simulated automatic rifle is higher, and the shooting hit probability is consistent with the actual effect of higher accuracy of close distance S1 live ammunition shooting.
In the double-optical coupling system, the light spot with smaller light beam diameter is transmitted along with the distance, the original distance of the light spot is still smaller, the laser power density keeps long distance, the effective shooting distance is obviously lengthened, the light spot is not large when the second laser module 2 with small light spot is at the long distance S2, the lower shooting hit probability of the simulated automatic rifle is generated, and the energy transmission of the laser with large light spot can not reach the position at the long distance S2 section, so the simulated shooting precision is consistent with the actual effect of high live ammunition shooting precision at the short distance S1.
The invention effectively solves the problem that the hit precision completely deviates from the hit result of live ammunition shooting in the simulation shooting. After double-light debugging, the laser can be directly used as a standard laser emission light source in an automatic rifle simulated shooting terminal, and the laser driving and modulation modes are completely consistent.
Therefore, the system is of an integral structure, and can be used as a single laser light source for adjustment in the laser adjustment process of the system, thereby effectively saving the adjustment time and improving the adjustment speed.
The key points of the invention are as follows:
1) according to the invention, the beam combining mirror 4 is used for combining the first laser module 1 with the small-spot second laser module 2 into one laser beam for outputting, but one laser beam has two characteristics of a large spot and a small spot, so that the high hit probability of the close-range S1 live ammunition shooting of the large-spot close-range S1 simulation automatic rifle is realized, and the low hit probability of the long-range S2 live ammunition shooting of the small spot at the long-range S2 simulation automatic rifle is realized.
2) The mounting structure and the reflection and transmission functions of the beam combiner 4.
3) The angle adjusting joint 5 is a preposed spherical omnidirectional adjusting joint.
