High Gain Infrared Collector and Data Node
An infrared collector employs a concentrator formed of a plurality of spatially related gradient-indexed (GRIN) lenses and a photo detector interconnected by optical fibers. Since the GRIN lenses are arranged on a hemispherical shell the concentrator is relatively insensitive to the direction of the incoming infrared radiation. Optical fibers are...
