ABSTRACT:
A holographic mirror is made by a process of continuous exposure. For this purpose, a photosensitive layer (10) is exposed strip by strip in a direction crosswise to that in which the layer is exposed by two interfering beams (6, 6'). Film (11) bearing photosensitive layer (10) is continuously moved in the longitudinal direction (F) at a speed that ensures sufficient exposure of the layer. The procedure makes it possible to produce holograms of any length in one direction.
