ABSTRACT:
A device for imaging penetrating radiation which includes a multiplicity of contiguously disposed fiberoptic tubes each of which is made of a very small diameter with an inner core material composed of scintillating material for converting radiation to light and a cladding glass about the inner core to serve as a reflector and a third and outer layer which is light absorbing to absorb light that is being emitted at too great an angle to the optical fiber axis to be guided to an exit end of the device. Also, one end of each of the fibers has a thin layer of a corrision resistent metal or metal alloy to cause light reflected back toward this end to be directed in an opposite direction to the output end of the fiber and by this reflection cause the output to be considerably increased over that which would be lost if no reflecting means were placed at the end of each of the fibers.
