DEVICE FOR LOCATING POINT RADIATION SOURCES Russian patent published in 1997 - IPC

FIELD: location of point radiation sources including buries ionizing-radiation sources; environment monitoring; visualizing observed objects in ionizing radiation. SUBSTANCE: device has three similar unidimensional coding masks arranged on one plane on sides of equilateral or 45 deg. right triangle with m elements in each mask. Three similar unidimensional position-sensing detectors with m sensing elements in each detector are placed at distance a from respective masks. Each detector element is provided with detector light guide with recovery mask on its output that has m elements in the form of color light filters scattered over transmission spectrum. Sequence of elements in each next mask of each group of m recovery masks is shifted through one element in cyclic manner. Output of each sensing element of recovery mask is connected via light fiber with screen strip color mixing element. One screen strip element is connected to all elements of recovery mask bearing sequence numbers same as those of respective elements of screen strip. Each of three screen strips has m elements, each being connected to light guide. Light guides form display screen graticule. EFFECT: enlarged functional capabilities. 3 dwg
