Abstract

The recording and reconstruction of a multicolor image from a plane hologram by spatial filtering in the Fourier plane are discussed. Conditions under which the reconstructed images are free from color crosstalk are described and analyzed. Experimental results for confirming the analysis by a two-color reconstruction is presented. The spatial filter size and the information recording capability are determined from hologram recording parameters. It is found that the resolution capability of this method is adequate for many practical applications. Methods for recording and reconstruction of multicolor images without an imaging lens are also discussed. Many possible applications are suggested.
