Abstract

Optical information transfer methods are limited in capacity to transfer information by the number of available information channels. This system renders the capacity to transfer information independent of the number of information channels and only dependent on the bit storage capacity of the particular areas of the optical memory.

Optical Information Transfer System

Optical information transfer methods are limited in capacity to transfer information by the number of available information channels. This system renders the capacity to transfer information independent of the number of information channels and only dependent on the bit storage capacity of the particular areas of the optical memory.

The system comprises conventional, two-dimensional light deflector 3 which accepts a beam of light provided by source 1 and focused by lens 2. Deflector 3 has a fixed number of information channels and focuses a light beam to one of a fixed number of areas of photographic memory 4. The number of memory areas is equal to the number of information channels of deflector 3. Each area A1, A2, etc., of memory 4 contains a plurality of bits of information which are illuminated simultaneously. Thus, the number of bits capable of being accessed at any one time by the light beam is equal to the product of the number of information channels of deflector 3 and the number of bits in an accessed area.

All information of a selected area is imaged on interrogation plane 6. Imaging is performed by array 5 of fly's eye lenses. Each lens in the array is required to have the same f/number as deflector 3. Plane information channels of deflector 3 and the number of bits in an accessed area.
