Abstract:
1. A direction sensitive detector for measuring radiation from afar, comprising: a first radiation detection system including: light receiving elements respectively connected to each end of said scintillating optical fiber and operable to convert the light signal propagating in two directions along said scintillating optical fiber into electric signals; and a radiation analysis system operable to derive an incident position of the radiation based on a difference between arrival times of the electric signals from said light receiving elements; a second radiation detection system including: wherein each of said first radiation detection system and said second radiation detection system further includes a fiber guide having an outer surface curved in a semicircular shape and a groove formed along said outer surface, a plurality of scintillating optical fibers being housed in said groove, and a plurality of flat collimators being fixed to said outer surface of said fiber guide.
