Abstract
Method and Apparatus are provided for visibly outlining the energy zone to be measured by a radiometer, the method comprises providing a laser sighting device on the radiometer adapted to emit more than two laser beams against a surface whose temperature is to be measured and positioning said laser beams about the energy zone to identify said energy zone. The apparatus comprises a laser sighting device adapted to emit more than two laser beams against the surface and means to position said laser beams about the energy zone and to identify said zone. A primary laser beam is passed through or over a beam splitter or a diffraction grating and formed into a plurality of secondary beams which produce on the target surface a pattern which identifies the zone investigated with the radiometer. Laser light may be directed axially to illuminate the central area of the zone.
