A target for optically activated seekers and trackers (TOAST) which provides for calibrated and variable target characteristics such as size, intensity, spatial position, color and interfering background. The TOAST has a first ilumination system providing a target light beam through an adjustable iris which controls image size. The target beam passes through a collimator lens which focuses the light at infinity. With the target beam focused at infinity, the motion of an elevation plate lengthens or shortens the distance from the collimator lens to a one motion mirror. The target beam is attenuated by a variable filter driven by a servo-motor, and a color selection process is provided by passing the beam through spectral filters. A focusing lens and attendant mirror lengthen or shorten the distance from the one motion mirror to the focusing lens and mirror, which is orthogonal with the one motion mirror, thus providing an X-Y movement of the target image formed by the focusing lens. The target image is formed in a plane and reflected by a beamsplitter mirror to a main objective lens which emanates the light focused at infinity. A background light beam with background imagery is provided to the beamsplitter mirror and mixed with the target image so as to simulate the target environment encountered by an operating optically activated seeker and tracker.
