Abstract
A weapons training simulator in which a multilayer composite movie film fed of a normal film for projecting a non-polarized image of target and background and a polarized film for projecting a polarized target image is utilized in a projector to project the polarized and non-polarized images on a non-depolarizing screen and in which a weapons mounted polarized light sensor circuit is provided to indicate target hit or miss as the weapon is aimed and fired. The invention also contemplates intentional non-registration of the normal and polarized films by a number of frames selected to represent the correct target lead to properly hit the moving target.
