Abstract

A system for displaying target information on a realistic simulated targetcene presented by a motion picture film projector. The target information is derived from laser carrying weapons which are aimed at the simulated targets. The impact point of the laser beam on the target screen are optically projected onto the target screen as spots to provide a visual presentation of the distribution of fire of the laser carrying weapons.

Claims

1. A system for showing the distribution of gun weapon fire on a screen upon which are projected moving targets and wherein a pulse laser beam is directed at respective moving targets when said weapon is fired, said system comprising:

a TV camera having its pick-up lens focused on said target screen;

means in front of said pick-up lens for permitting only reflected laser beam pulses to pass to said TV camera to produce respective spots corresponding to respective laser pulses; and

means responsive to the output of said TV camera for optically projecting said spots on said screen whereby the respective spots provide a visual indication of a hit or miss of a selected target on said screen.

2. The system in accordance with claim 1 wherein said first mentioned means comprises a narrow band optical filter centered at the frequency of said laser beam.

3. The system in accordance with claim 2 wherein the center of said narrow band filter is 0.81 micrometers.

4. The system in accordance with claim 1 wherein said TV camera includes a vidicon type tube having a spectral peak between 0.8 and 0.9 micrometers.

5. The system in accordance with claim 4 wherein said first mentioned means comprises a narrow band optical filter centered at the frequency of said laser beam.

6. The system in accordance with claim 5 wherein the center of said narrow band filter is 0.81 micrometers.
