ABSTRACT:
An apparatus for use in determining the temperature of or at a specific area by measuring the infrared radiation from that area through the use of a reflector structure to direct the radiation from the area to an infrared detector can be improved by using a laser to provide two light beams which are directed so as to intersect at a distance from the apparatus corresponding to the principal focus of the reflector structure.
