Abstract : The patent application describes a simulator including an improved holographic heads up display system in which the projection of images, via a plurality of slide projectors, through several light ray channels or paths, are controlled by polarizer light valves, associated one with each respective channel, and the output or outputs of the channels dependent upon the on-off conditions of the several light valves, is passed through a holographic lens as a window to the eye of an observer. Means are also provided to maintain a desired light level intensity at said window by coordinated adjustment of the light valves. A further aspect of the invention contemplates the provision of vehicular control means connected to recording charts on which a prerecording of correct response to a programmed display has been made on each chart to compare the actual trainee controls movement with the proper movement for the exercise.
