Paper Abstract

The permanent storage of true 3-D images in computer-generated rainbow holograms is proposed and tested. The procedure is of special interest in situations where image data are acquisitioned by computer like in tomography. A l-D Fourier transform lowers the requirement on memory space and allows short handling times. The spectra of different planes in depth of the object are repeated to form a hologram using a minimum of computation time but of a size sufficient for display. The spectrum of each object plane perpendicular to the optical axis is superposed with a quadratic phase factor. Full horizontal parallax is preserved. The reconstruction is accomplished in collimated white light.
