Calibration source of high luminance with integrating sphere based on Jones method

In order to meet the requirements of laboratory radiometric calibration for continually rising optical aperture of optical remote sensors, a calibration source of high luminance with integrating sphere was designed based on Jones method. The integrated radiance in the range of 400 nm to 900 nm was 6 800 W/(m2sr). The thermal design results indicated that the water-cooling method could meet the heat dissipation of the high luminance calibration source. The integrated radiance of the high luminance calibration source was 6 714 W/(m2sr) in the range of 400 nm to 900 nm. The temperature distribution of the integrating sphere made the calibration demands satisfied through water-cooling, which suggested that the calibration source of high luminance using integrating sphere based on Jones method could be used to engineering practice.
