Compound optical projection system - has partially combined light paths to show two differently based images on same flat plane

摘要

The projector superimposes, in the same space (11), a black based image of an object (12) on a clear based second image. An optical system (13,14) forms a black based image by lighting one object using a system of occultation or light deviation and a second optical system (14,15) forms the clear based image. The optical systems have a partially common axis (10) and common sections downstream in the direction of light propagation. The system forming the clear image uses the occultation system downstream.
