Device for implementation of a temperature reference in a camera for detecting infrared radiation, and a camera comprising said device

摘要

In an infrared-radiation detecting camera the following are provided: an optical path with at least one collimator (5) and one scanning mirror (7); infrared-radiation detecting means (11); and at least one temperature reference with a radiating surface (31A) at a controlled temperature. The temperature reference comprises a reflecting prism (17) which receives a radiation emitted by the radiating surface and reflects it in the optical path towards the detecting means (11). <IMAGE>
