ABSTRACT:
In an optic relay device having a memory the image to be treated is projected on a photoconductive element and is transformed into a charge image stored in a memory in the proximity of a plate of electro-optical material brought at its Curie point.
The electro-optical material and the photoconductive element are such that the Curie temperature of the electro-optical material is near the temperature of the maximum sensitivity of the photoconductor.
