System of aligning laser transmitter for direct-fire weapons and method

The present invention relates to an alignment system of a laser launcher mounted on a true fire.

In the military, as one of the soldiers' training courses, the Multiple Integrated Laser Engagement System (MILES) is used. It refers to a virtual training system that transmits digital information in real time.

Specifically, by attaching a laser launcher for firing a laser to a personalizer such as a rifle or a grenade, and using a laser detector on the other side, it is possible to know whether or not to hit by firing and detecting the laser even without actual shooting. Through this, it is possible to engage in training without actual killing, and as a result, it is possible to increase the soldiers' ability to deal effectively and the operational efficiency of the commander.

In addition, as survival games have become increasingly popular not only for the military but also for students, young general people, and the like, they have used small bullets filled with paint, but recently, the number of game sites using lasers has increased.

On the other hand, in the above-described simulation engagement training, survival game, etc., a firearm equipped with a laser launcher (fire engine or simulator) is required. 1 is an illustration showing an example of a firearm equipped with a laser launcher. Referring to FIG. 1, a laser launcher 12 is mounted to a barrel of the firearm 10. As shown in Figure 1, the central axis (b) of the laser beam emitted from the laser launcher mounted on the firearm should be parallel to the line of sight (a) of the firearm and the direction in which the bullet of the firearm travels and the laser beam of the laser launcher This traveling direction b must be the same. Here, the aiming line (a) means a straight line from the shooter's eye to the target aiming point through the aperture and the anchor.

Therefore, the process of aligning the direction of the laser launcher and the aiming line of the firearm to be parallel to each other is essentially required. Conventionally, a zero sight is used to align the laser launcher, the zero aim is not only a very expensive equipment, there is a problem that typically takes 15 minutes or more to complete the laser beam alignment.

In addition, the alignment system of the laser launcher according to the present invention can be installed in a narrow space within the quarter, unlike the conventional alignment system that should normally secure a distance of 25m, the user can determine the position of the laser beam through the screen of the display unit Alignment can be done with direct confirmation, allowing for quick and accurate alignment.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the alignment system of the laser launcher mounted on the true fire according to the preferred embodiment of the present invention.

Figure 2 is a schematic diagram showing the overall alignment of the laser launcher according to an embodiment of the present invention.

Referring to FIG. 2, the alignment system 2 of the laser launcher mounted on the firearm according to the present invention is a firearm supporter 20 for fixing the firearm 10 on which the laser launcher 12 is mounted, and the firearm is aimed at. A target 30, a camera 40 for capturing an image of the target, and a display unit 50 for displaying an image captured by the camera is provided.

Referring to FIG. 3, the firearm supporter 20 is a support for fixing the firearms 10 to be aligned with the laser launcher so as not to move, and a fixing rod 22 and a vertical height which can fix the front of the firearms. It consists of an adjustable top and bottom adjustment screw 21.

The target 30 is arranged at a distance from the true fire support, and the muzzle and laser launcher of the true fire target is arranged to aim at the target. In this case, the separation distance 'd' between the target and the laser beam firing period is preferably about 5 m. It is possible to align in fairly narrow spaces, given that a distance of 25 m is normally required in conventional alignment systems.

On the surface of the target 30 opposite the muzzle of the true fire machine, a true fire target line and a laser target line are displayed. 4 is a schematic view showing the surface of the target by way of example, in order to help the understanding of the present invention, the infrared LEDs constituting the laser target line is expressed in red unlike the actual color. Referring to FIG. 4, the firearm target line 32 of the target 30 is for a user to aim the firearm of the firearm with the naked eye, and is preferably configured in a cross (+) shape. The laser target line 34 of the target 30 is for aiming a laser launcher that emits a laser beam in an infrared band, and it is preferable to arrange a plurality of infrared LEDs in a cross shape (+).

The center of the true fire target line 32 is the target point of alignment of the true fire line aiming line, and the laser target line 34 travels from the laser launcher fixedly mounted on the outer circumferential surface of the barrel of the true fire machine. Since it is disposed in, the true fire target line and the laser target line is disposed at a predetermined distance apart. Thus, the separation distance and position between the center point 'A' of the true fire target line 32 and the center point 'B' of the laser target line 34 is determined by the laser launcher attached to the barrel of the true fire machine. It depends on the location.

The camera 40 is equipped with a visible light blocking filter 42, the image of the visible light band of the image of the target is cut off, and only the image of the infrared band passes through the image. Thus, the true-fire target line of the target is not photographed, only the laser target line that emits infrared rays and the laser beam of the laser launcher that reaches the target are captured. The camera support 44 is preferably used to fix the camera 40 so that it does not move toward the target.

5 is a graph showing the characteristics of the visible light cut filter 42. Referring to FIG. 5, the visible light blocking filter shows a transmittance of almost 0% in the wavelength band of 700 nm or less, shows a transmittance of almost 98% or more in the wavelength band of about 800 nm, and almost 0 in the wavelength band of about 2200 nm or more. The transmittance of% is shown.

Therefore, when the visible light blocking filter having the above characteristics is mounted on the camera, light in the visible light band is blocked and light in the infrared wavelength band emitted from the laser target line and the laser beam, which is a wavelength band of 905 nm, is incident on the camera. .

The image signal for the image photographed by the camera 40 is transmitted to the display unit 50. The display unit 50 receives an image signal from the camera 40 and displays it on a screen. The camera 40 and the display unit 50 may be connected by a wired cable 60 or wirelessly by using a wireless communication module for an image signal.

Hereinafter, referring to FIG. 6, a method of aligning a laser launcher mounted on a true fire machine using an alignment system of the laser launcher having the above-described configuration will be described sequentially.

First, the user fixedly arranges the firearm 10 equipped with the laser launcher 12 to be aligned on the firearm supporter 20 (step 500), and then the line of sight of the firearm 10 is moved to the target 30. Adjust to accurately target 'A', the center point of the true fire target line 32 (step 502).

Next, the operation switch of the laser launcher 12 is turned on to emit a laser beam, so that an image of the target is captured and displayed on the display unit (step 510). The user checks the image displayed on the display unit 50 (step 530). 7 illustrates an image of a target displayed on the display unit 50 by way of example. Referring to FIG. 7, it can be seen that the arrival position 'C' of the laser beam reaching the target is deviated from the center 'B' of the laser target line. When firing the laser beam from the laser launcher, the trigger can be triggered in the bulletless firing mode, or by connecting the bulletless firing switch provided for maintenance and inspection to most laser launcher, and reaching the laser beam from the image of the display unit 50. It is advisable to repeatedly press the bullet-free firing switch so that the position can be determined.

If the arrival position ('C') of the laser beam of the target and the center ('B') of the laser target line exactly coincide (step 540), the line of sight of the true fire and the laser launcher are judged to be correctly aligned and aligned. The job ends (step 550).

If not, the user checks the degree of the laser beam deviating from the laser target line through the image displayed on the display unit, and moves the laser beam adjustment button provided in the laser launcher in the up / down / left / right directions of the laser beam. After the orientation is adjusted (step 560), the process returns to step 510 to repeat the alignment.

Although the present invention has been described above with reference to preferred embodiments thereof, this is merely an example and is not intended to limit the present invention, and those skilled in the art do not depart from the essential characteristics of the present invention. It will be appreciated that various modifications and applications which are not illustrated above in the scope are possible. And differences relating to such modifications and applications should be construed as being included in the scope of the invention defined in the appended claims.
