ABSTRACT:
Optical assemblies are disclosed for use in producing an effect of three-dimensional relief in the projection of a still photograph or motion picture film by means of polarized light, each still photograph or frame of the motion picture film comprising a single, regular, two-dimensional image. In order to produce the effect of three-dimensional relief the projector is provided with an optical assembly consisting of a lens and a beam-splitting polarizing device located inside the lens barrel which results in the projection of two oppositely polarized and laterally separated images of the photograph or each frame of motion picture film. The screen is of the non-depolarizing type and the images are seen in three-dimensional relief when viewed through polarizing spectacles.
