White-light stereoprojection through Fourier spectrum polarization

Abstract

Theory and experiments of a new stereoprojection technique that uses a white-light optical image-processing system are described. The stereoprojection can be accomplished in two steps: (1) spatial encoding of stereoscopically coupled images and (2) spatial polarization filtering at the Fourier plane in a white-light optical image processor. Compared with existing stereoprojection methods, the present technique requires only one projector and a single piece of encoded film; therefore it is much simpler and more economical to use for practival applications.
