Abstract
The invention has for its object a reading arrangement which uses a source functioning by pulses and delay-action dividing optical means which successively ensure the illumination of M storage areas of the recording, each area comprising P bits 0 and 1. Thus, a single reading pulse makes possible the reading, with a mosaic of P photodetectors, of a block which comprises M words of P bits. The invention is particularly applicable to non-destructive optical reading stores, for instance holographic stores.
