Abstract

The process of forming holograms calculated by computer uses a device normally designed for producing masks for integrated circuits. The device has a radiation source (10, 13) and a support (14, 141) which is sensitive to the radiation. The device has a displacement system which is displaced relative to the radiation source (10, 13) and the support (14, 141). The displacement system has a first carriage designed to be rapidly displaced with an alternating movement in a first direction. The carriage carries the source (10, 13) or the support (14, 141). A second carriage is designed to be displaced relatively slowly in a second direction which is perpendicular to the first direction. Movement of the second carriage takes place in the same time as displacement of the first carriage. The second carriage carries the recording support (14-141) or the source (10-13). The device also includes transmission of data, relative to a hologram, to a computer which controls the radiation source.
