Description

  The present invention relates to a laser aiming device that is mounted on a firearm such as a rifle, a handgun, a machine gun, a heavy machine gun, and the like to aim a target.

  Conventional laser sighting devices generally use a night vision device at night and use a low-power invisible laser, and cannot be used during the daytime. On the other hand, a sighting device using a visible laser was common during the daytime. Therefore, it was necessary to replace each sighting device depending on the operational status, or to attach both to the firearm. All of these contents were difficult to operate and were not economical.

In order to solve this problem, there is a method of configuring a sighting device in which a non-visible laser and a visible laser are integrated. In the conventional technique, it is necessary to configure an independent optical system for each of the non-visible laser and the visible laser. In addition, the structure must be large, and the optical axis adjustment mechanism of the laser must also be configured. As a result, the operability deteriorated with the increase in mass and the economy (easy procurement) deteriorated.

  As shown in FIG. 2, the remote switch 17 is a switch operated by a user who is a member, and when the button of either the invisible laser or the visible laser is pressed, the control circuit 22 is turned on (ON) / off. It is output as an (OFF) signal. As another method, there is a method in which a SW for selecting an invisible laser / visible laser is provided in the laser aiming device main body, and the remote SW operates only an on / off signal. Either method is feasible.

  In the control circuit 22, a circuit for controlling the selected laser type is configured, and a non-visible laser control signal, a visible laser control signal, and an enemy team identification laser control signal are selected and output. The non-visible laser control signal, the visible laser control signal, and the enemy friendly laser control signal from the control circuit 22 correspond to the non-visible laser drive circuit (DRV1) 26, the visible laser drive circuit (DRV2) 27, and the enemy friend identification, respectively.

A switch (SW) 23 is connected between the control circuit 22 and the visible laser drive circuit 27, and the switch 23 is always set to ON, and is configured to be OFF for a predetermined period when an OFF signal is input. The

  The invisible laser drive circuit 26, the visible laser drive circuit 27, and the enemy friendly laser drive circuit 28 correspond to the invisible laser control signal, the visible laser control signal, and the enemy friendly laser control signal from the control circuit 22, respectively. When input, a non-visible laser drive signal, a visible laser drive signal, and an enemy friendly laser drive signal are displayed as an invisible laser oscillation source (LD1) 29, a visible laser oscillation source (LD2) 30, and an enemy friendly laser oscillation source.

It is input to the light receiver 19 of the device 13.

  The light receiver 19 extracts only the IFF transmission pulse from the reflected light from the reflector 14 and receives it as IFF received pulse light. The IFF received pulse light from the light receiver 19 is output to the detection circuit 25. The detection circuit 25 converts the IFF reception pulse light input from the light receiver 19 into an electrical signal and outputs it to the post-comparator 24 as an IFF reception pulse.

  The switch 23 receives the transmission off signal from the comparator 24 and stops the output of the high-power visible laser oscillation source 30 for a predetermined period. The stop / start of the output of the high-power visible laser oscillation source 30 is held during the pulse interval of the IFF transmission pulse.

  FIG. 3 is an output timing chart of the visible laser according to the embodiment of the present invention. As shown in FIG. 3, when the output of the visible laser is turned on by the remote switch 17, the visible laser beam is output from the high-power visible laser oscillation source (LD2) 30, and at the same time, the enemy friendly laser oscillation source The laser light for identifying an ally (IFF transmission pulse) is repeatedly output from (LD3) 31 for a period during which the remote switch 17 is pressed at a constant cycle.

  The IFF reception pulse obtained by receiving light by the light receiver 19 is constantly compared with a threshold value by the comparator 24 and, when the threshold value is exceeded, a gate signal (turns off the output signal of the high-power visible laser oscillation source (LD2) 30). Output pause gate). This gate signal is input to the switch 23 to perform on / off control for the visible laser driving circuit (DRV2) 27.

  The visible laser is used when aiming the target with the naked eye during the daytime, and the non-visible laser is used when aiming at the target using the night vision device at night. In addition, the enemy-friendly laser (IFF transmission pulse) is used simultaneously with the visible laser, and when aiming the high-power visible laser, the aiming near the eyes is interrupted when the teammates' eyes are accidentally aimed. Used as a safety function.

  As described above, the laser sighting device according to the embodiment of the present invention inputs a multi-wavelength laser output to an optical mixer by an optical fiber without passing through an optical system, and only selects the selected laser output by the optical fiber. It outputs to two optical systems, and forms a desired aiming laser beam.

  In addition, a visible laser for daytime use requires high output power to ensure visibility in the outdoors. Therefore, a laser pulse (IFF) that distinguishes enemies and allies in order to ensure the safety of teammates' eyes. (Transmission pulse) is output at the same time as the aiming laser, and the reflected light (IFF reception pulse) from the reflector placed on the front of the teammate's helmet (in the vicinity of the eyes) is received and processed in the vicinity of the eyes. In this case, a safety function is provided that immediately stops the output of the visible laser in the event of a failure.
