Abstract: In a weapons training simulator, laser radiation is output via optics (28) to simulate the firing of a round, and reflected radiation received via a conjugate path to assess the effectiveness of the shot. In the event of a miss a scan of the target area is required to provide fall of shot information. The scan is performed by controlled movement of the output faces of fibre optics (23, 24, 25) flexibly coupling to fixed sources (20, 21, 22) and of the input face of a fibre optic (200) flexibly coupling to a fixed detector (201). The problem of the bulk and inertia of prior art systems is improved by the remote location of lasers, drive and control, which may be conveniently separated for service or replacement without disturbing the optically aligned input and output faces. A further improvement is that vertically aligned multiple sources may be employed without undue weight penalty, yielding elevation information from a lateral scan.

Abstract: A flying spot scanner is used to expose a photosensitive surface to an intensity modulated beam of light to build up an image on the photosensitive surface.
