A New Kind of Integrating Sphere Radiation Calibration System for Satellite Remote Sensors
A new kind of half integrating sphere radiation system that has the adjustable area of radiating surface in the 380nm-2500nm wave band is introduced in this paper. The opening diameter of the integrating sphere reaches to Φ600mm. Half Integrating sphere radiation system is mainly composed of a half sphere, extension part, cyclic annular baffles and other components. The diameter of half-integrating sphere is Φ1800mm. The radiance uniformity through opening reaches up to 98%. Systems can now be used for all types of large field of view of satellite remote sensor for the calibration of spectral radiance; in addition, it can also be applied for various types of light exposure calibration such as flash lamp and so on.
