摘要

A holographic mirror is made according to a continuous exposure process. For this purpose, the photosensitive layer (10) is exposed, band by band, in the direction transverse to a beam of laser rays (6) at a predetermined angle of incidence alpha . The film (11) carries the photosensitive layer (10) and is displaced continuously in the longitudinal direction (F) at a speed which ensures sufficient exposure of the layer. The process enables holograms to be made which have any length in one direction.
