光学遥感器应用及宽动态范围探测技术发展趋势

Currently, optical remote sensors have been widely applied in basic scientific research such as meteorology, oceanography, resource survey, environmental monitoring, as well as in cutting-edge national defense and civilian applications [1-3]. Achieving high-precision detection with a wide dynamic range is one of the important trends in the development of optical remote sensors. For example, the dynamic range of the radiance measurement of the American VIIRS DNB micro light channel reaches 10 orders of magnitude [4]; the measurement dynamic range of the domestic dawn-dusk orbiting satellite payload is about 9 orders of magnitude [5]; and the technology for detecting and calibrating nonlinear measurements in the range of fA-μA at the 10-order magnitude level is required for the solar reflectance spectral space radiation reference payload [6].
