ABSTRACT:
A composite photography system of a registered matte type having foreground and background camera optical systems is provided. The respective images from each camera optical system are maintained in registration whereby objects in the background scene can be viewed by one camera and objects in a foreground scene can be viewed by the other camera to produce a realistic composite image. The optical systems permit the maintenance of a substantially constant magnification ratio of image to object during a variable focussing of at least one of the foreground and background optical systems. Additionally, substantially stationary entrance pupil positions are maintained during the focussing mode of operation. The background lens system is, by itself particularly adapted for incorporation into optical scanning probes such as simulators to provide a minimum altitude and constant image magnification during focussing.
