A light activated solid state microwave generator capable of providing radio frequency pulse bursts includes a plurality of optoelectronic switches arranged on a common substrate for simultaneous activation thereof and a plurality of distributed transmission lines connected in series and properly terminated by the switches upon activation by light.

Light activated solid state microwave generators

A portable holographic information retrieval system is described in which individual holograms each of which contains the alphanumeric information from an individual page of a book, are reconstructed on a rear-illuminated viewing screen. The individual holograms are contained on a permanent transparency as a matrix, the holograms of successive pages of a book being arranged in a sequential manner. The entire matrix of individual page holograms is contained on a transparency which is approximately equal in size to a standard 35 millimeter photographic slide. The reconstruction apparatus has the rear-illuminated viewing screen collapsibly mounted to a system housing. The housing includes a small source of a collimated beam of light for illuminating a selected 'page' in the transparency. The transparency is mounted on a carriage which is capable of being traversed relative to the illuminating collimated beam of light so that an individual page hologram may be reconstructed by having a real image formed on the viewing screen. When collapsed for storage, the portable retrieval system is approximately the size of a standard volume.
