Abstract

A laser transmitting device for marksmanship training. The device is readily mountable to the barrel of a firearm and transmits a light beam upon the actuation of the firing mechanism of the firearm. The laser device is triggered in response to an acoustical transducer which detects sound energy developed by the firing mechanism of the firearm, and means are provided to prevent false triggering of the device by extraneous sounds. The light beam is detected by a target having a plurality of light detectors, whereby an indication of the accuracy of the aim may be obtained.

Claims

1. A device, adapted to be mounted on a firearm, for transmitting a beam of light upon actuation of the firing mechanism of the firearm, said device comprising:

means for transmitting a light beam; and

means for triggering said transmitting means in response to acoustical energy developed by the firing mechanism of said firearm.

2. The device of claim 1 wherein said triggering means includes a transducer for converting the acoustical energy to electrical energy.

3. The device of claim 2 wherein said transducer is a crystal

4. The device of claim 2 wherein said triggering means includes means for rejecting energy outside of the frequency range of the energy developed by the firing mechanism.

5. The device of claim 4 wherein said means for rejecting energy includes a highpass filter network.

6. The device of claim 4 wherein said means for rejecting energy includes a passband filter network.

7. The device of claim 4 wherein said means for rejecting energy includes a crystal which substantially responds to energy in the frequency range of the energy generated by the firing mechanism.

8. The device of claim 1 wherein said transmitting means includes a laser diode;

and driver means for activating said laser diode with said driver means including an electrical storage element, and means for preventing repeated actuations of the laser diode for a selected time period after it has been previously activated.

9. The device of claim 8 further comprising a source of potential coupled to said driver means with said means for preventing repeated actuations including a resistor coupled in series with said source of potential and said electrical storage means.
