Title: MEASUREMENT DEVICE AND METHOD FOR SPECTRAL RESPONSIVITY OF LARGE-APERTURE RADIOMETER
Abstract:
A measurement method for spectral responsivity of a large-aperture radiometer (6), relating to the field of optical measurement and test. The method comprises: first generate monochromatic light by using a monochromator (14); then the monochromatic light enters a small-aperture integrating sphere (15); finally generate large-aperture uniform monochromatic parallel light subsequent to performing beam expansion by using a collimation system (16), and achieve measurement of spectral responsivity of a large-aperture radiometer by using a small-aperture light beam scanning detection method. Compared with the prior art, the present invention can achieve measurement of absolute spectral responsivity of a large-aperture radiometer by using a small-aperture light beam scanning detection method, and based on an established standard large-aperture radiometer (3), achieves measurement of spectral responsivity of a measured large-aperture radiometer by using a comparison method, and thus, a measurement process is simple, experimentation is convenient, and measurement time is greatly reduced. Also disclosed is a measurement device for spectral responsivity of a large-aperture radiometer.
