Abstract
A method and apparatus for simultaneously training multiple trainees in the use of simulated weapons, which method defines a set of image shapes and assigns each image shape to a different simulated weapon capable of generating a light beam, at a selected wavelength, having the assigned image shape. By collecting data under control conditions and evaluating a set of parameters that uniquely identifies each image shape and by comparing the resulting "control parameters" to the same set of parameters evaluated under training conditions (thereby, producing "on-line parameters") each image shape produced during a training session is identified and associated with a simulated weapon. The method enables an expanded number of trainees to be simultaneously trained, by employing the same set of image shapes produced and detected at different wavelengths. In accordance with the preferred embodiment, the apparatus includes a plurality of simulated weapon having a light source, a reflective surface, a light data acquisition assembly, and a controller to analyze and compare collected data. The light data acquisition assembly comprises a rasterizing sensor (i.e., a CCD camera), wavelength filter…
