Abstract

The measurement of sky background infrared radiation is one of the important means to obtain background photoelectric characteristics. For general atmospheric measurement software, regional differences are ignored and particular area sky background optical properties can’t be reflected. A measurement method of sky background infrared radiation characteristic based on infrared image inversion is proposed to solve all these problems mentioned above. Firstly, radiation responsiveness is determined by calibrating the infrared measurement equipment. Secondly, using the equipment, sky background image, atmospheric transmittance and atmospheric path radiation data are obtained. Finally, according to the radiation responsiveness of the measuring equipment and atmospheric transmittance data, the sky background infrared radiation is inversed. The experimental result shows that the sky background luminance data of the proposed method and LOWTRAN7 are in good agreement, meeting the needs of practical application.
