Abstract:
An infrared radiation detecting device comprising a hermetically sealed housing, the housing having a generally cylindrical shape with a proximal end and a distal end, a distally facing opening formed in the distal end, a detector and circuitry arrangement mounted within the distally facing opening, a power supply mounted within the housing proximal of a substantial portion of the detector and circuitry arrangement, the detector and circuitry arrangement including a distally facing radiation detector, a microprocessor capable of receiving a signal from the detector, the signal being reflective of a level of radiation being detected, the microprocessor controlling an output from a speaker based upon the level of radiation being detected; the microprocessor also controlling an output from an optical indicator based upon the level of radiation being detected, and the microprocessor capable of expanding a spike signal reflecting a fleeting detection of infrared radiation.
