Subliminal image modulation projection and detection system

摘要

Weapon training simulation system including a computer (40) operated video display scene (24) whereon is projected a plurality of visual targets (34). The computer (40) controls the display scene (24) and the targets (34), whether stationary or moving, and processes data of a point of aim sensor apparatus (32) associated with a weapon (30) operated by a trainee (28). The sensor apparatus (32) is sensitive to non-visible or subliminal modulated areas having a controlled contrast of brightness between the target scene (24) and the targets (34). The sensor apparatus (32) locates a specific subliminal modulated area and the computer (40) determines the location of a target image (34) on the display scene (24) with respect to the sensor apparatus (32).
