Abstract
A scanning laser helmet mounted sight that determines helmet or sight position from externally mounted light sources and detectors. No electronics, including light sources and detectors, are on the helmet. Also, no electrical cables or mechanical linkage is connected to the helmet. The helmet has passive reflectors for reflecting a scanning light beam from a laser source. The return times and directions of the returning light beam relative to a return of a light beam from a reference point, processed by the off-helmet electronics, result in a position indication of the helmet.
