Abstract

The invention relates to the technical field of optical tests, in particular to an external field type infrared radiometer. According to the infrared radiometer, a main convergence mirror is connected with a wave chopper; the wave chopper is connected with a standard reference black body source and light filters; the light filters are connected with neutral attenuation pieces; the neutral attenuation pieces are connected with optical spectrum correcting pieces; the optical spectrum correcting pieces are connected with an infrared detector; a signal acquisition part is connected with the infrared detector and the wave chopper respectively. Through the embodiment, a corresponding optical spectrum curve of a whole system in a measurement waveband can be enabled to be a flat curve through the optical spectrum correcting piece, the linearity and the measurement accuracy of the whole system are improved, and the influence of a radiation spectrum of a tested object on a measurement structure is avoided; the neutral light filters with different attenuation ratios are adopted and the dynamic range of equipment is expanded. Therefore, the equipment has a plurality of ranges and strong and weak radiation targets can be measured.

Description

technical field [0001] The invention relates to the technical field of optical testing, in particular to an outfield infrared radiometer. Background technique [0002] Radiometry is a science that studies the measurement of electromagnetic radiation energy. For different frequency bands of electromagnetic radiation, due to its particularity, there are often different measurement methods and methods. For infrared bands, radiometers are generally used to measure radiation values. Depending on the application, the measured values ​​generally include irradiance, radiance, and radiant intensity. [0003] In recent years, with the application of infrared technology more and more widely, people pay more and more attention to the measurement of infrared radiation, especially in the military field, the combat performance and stealth performance of various infrared guided weapon systems under complex infrared background conditions are getting better and better. It has received more a...
