ABSTRACT:
Achromatic volume holograms are attained for broad band phase conjugation and image reconstruction having bandwidths of 250 nanometers. The holograms are generated by means of a diffraction grating having a predetermined angle of tilt. Achromaticity is achieved by tilting the holographic recording medium at the same predetermined angle.
