Terry M Trumble: Ultraviolet wavelength smoke detector. The United States of America represented by the Secretary of the Air Force, Joseph E Rusz, Robert Kern Duncan, September 21, 1976: US03982130 (38 worldwide citation)

Collimated ultraviolet light radiation at wavelengths of 2537A and 3129A is alternately directed across the space to be monitored for smoke indicative of a fire. A "cats eye" mirror at the far side of the monitored space returns the ultraviolet rays to a photomultiplier detector adjacent the light s ...
