Abstract
An instrument for measuring radiation including a probe for collecting light. The probe includes a diffusive reflective surface at the forward end of the probe and an aperture block containing a pair of apertures to direct light reflected from the reflector to an optical waveguide and then to a light sensor and display unit.
Claims10
A probe for a radiation-monitoring device comprising:
- (a) a probe housing having a forward end and a proximal end;
- (b) a diffusive reflector mounted at said forward end of said probe housing, said diffusive reflector comprising a thin substrate attached to the lower side of said probe housing and a coating of diffusive reflective material on the upper surface of said substrate;
- (c) an aperture block mounted on said probe housing near said forward end and adjacent to said diffusive reflector, said aperture block provided with a pair of spaced apart apertures oriented to define a fixed size target on the coating of diffusive reflective material;
- and,
- (d) a light waveguide mounted within said probe housing, said waveguide having a forward end oriented to collect light reflected from said target area via said apertures, and a proximal end for emitting collected light.
