Abstract

The invention discloses an infrared radiometer and belongs to the field of testing of optical metrology. The infrared radiometer is used for measuring radiation temperature of a thermal infrared imager testing device and is mainly characterized in that the infrared radiometer adopts double optical paths, a detector in the infrared radiometer is respectively subjected to the radiation of the thermal infrared imager testing device and the radiation of an internal reference black body of the infrared radiometer, the temperature of the reference black body is controlled by a computer and is kept consistent with the internal temperature and environment temperature of the infrared radiometer, and solid angles formed by the two optical paths and the detector are identical and the two paths coincide through the design of a limiting diaphragm group and confirmation of the installing positions of the limiting diaphragms. The infrared radiometer has miniaturized and intelligentized characteristics and has the advantages of being high in measuring accuracy and wide in application prospect.

Description

technical field

[0001] The invention belongs to the field of optical metrology and testing, and relates to an infrared radiometer, in particular to an infrared radiometer for measuring the radiation temperature of infrared thermal imager testing equipment. Background technique

[0002] With the development of infrared imaging technology, thermal imaging cameras have been widely used in the military field. Since the 1980s, many domestic scientific research institutes and factories have successively introduced various types of thermal imaging camera testing equipment from the United Kingdom, Israel, the United States, France and other western countries for parameter testing of military infrared thermal imaging cameras. , Performance evaluation. Infrared thermal imager test equipment can be divided into single black body infrared thermal imager test equipment and background temperature controllable infrared thermal imager test equipment. In order to improve the measurement acc...
