| Abstract: | Relief-type holograms were copied on PVC sheets from a master made on a photosensitive As-Se-Ge amorphous film. One hundred hologram copies could be printed successively without degradation of the reconstructed image quality. Typical diffraction efficiency of the copied hologram was about 2%. |
