Abstract

The invention provides a spectral transmittance testing device for a large-caliber collimator, and belongs to the technical field of optical testing. The testing device comprises a standard surface element black body radiation source, a first three-dimensional adjusting table, an infrared radiometer, a second three-dimensional adjusting table, an adjustable supporting frame and a control computer;the standard surface element black body radiation source outputs radiation beams, the radiation beams enter an optical system of the large-caliber collimator of a measured photoelectric parameter measuring device; the infrared radiometer is used for receiving and detecting the emission radiation degree of the collimator, the measured data are processed and analyzed by the control computer to obtain spectral transmittance data; the first three-dimensional adjusting table is used for adjusting the radiation surface of the standard surface element black body radiation source to be perpendicularto the optical axis of the large-caliber collimator in the measured photoelectric parameter measuring device; and the second three-dimensional adjusting table is used for adjusting the infrared radiometer to be parallel to the optical axis of the large-caliber collimator in the measured photoelectric parameter measuring device and to be full of field of vision.

Description

technical field [0001] The invention relates to the technical field of optical testing, in particular to a spectral transmittance testing device and method for a large-diameter collimator. Background technique [0002] In recent years, space target detection has become an important research field at home and abroad, especially the use of infrared technology to detect space targets has attracted widespread attention from all countries. Target infrared radiation measurement is one of the basic technologies for obtaining target information, identifying and tracking targets. In order to complete the measurement of the infrared radiation characteristics of the target, the infrared optical system must carry out accurate performance test calibration during the development process and before the field use to ensure the accuracy of the measurement. [0003] The combined system using the black body radiation source and the collimator is a very important type of photoelectric paramete...
