Abstract: | A low-cost and simple color-encoding technique for holographic video memories is proposed and designated as a “stripe-coded” method. The playback system requires a laser of a single wavelength, a black-and-white vidicon installed TV camera and a common color TV monitor. One frame can be stored in a hologram of 4-mm diameter, and the storage density is several times higher than that of the conventional TV films. Color images of satisfactory hue and saturation were successfully restored. |
