Method and apparatus for measuring temperature using infrared techniques.

摘要

A method and apparatus are provided for visibly outlining the energy zone to be measured by a radiometer. A laser sighting device (12) is provided on the radiometer, adapted to emit at least one laser beam (14) against a surface whose temperature is to be measured, with said laser beam being positioned about the energy zone (E) to visibly outline said energy zone. This may be achieved by directing the beam (14) from the laser sighting device (12) onto a mirror (30) which is rotated by motive means (32) to deflect the beam to sweep out a circular path to define the energy zone (E).
