Abstract

The application of dyed gelatin to real-time non-Fourier image processing methods and polarization holography is described. Examples in contrast reversal of a transparency and subtraction and addition of two signals are presented. In the field of polarization holography interference gratings have been made with two beams having different polarization orientation between them; the polarization state of the diffracted orders has been studied.
