Reconstruction of a holographic image with radiation produced by a semiconductor laser screen

A cathode-ray tube with a laser screen was developed for optical holographic memories. A study was made of the influence of the parameters of a laser screen on the quality of the reconstructed image. An energy analysis of the reconstruction process indicated that 2·10³–2.5·10⁴ bits could be read in a pulse of 150 nsec duration with detectors of 10^–12–10^–14 J/bit sensitivity. A study of the achromatization of the reconstructed image was made.
