用一组窄带滤光片、简易辐亮度计和硅光二极管探测器设计了绝对型光谱辐亮度计。精确测量滤光片的光谱透过函数，计算辐亮度计的视场，标定探测器的绝对光谱响应度，成为绝对光谱辐亮度计，用来标定成象光谱和其它光学遥感器，并与基于光谱辐照度灯进行辐射定标的传统方法进行了比较。结果表明，基于探测器进行辐射定标的方法是一种提高光学遥感器定标精度的途径，而且是佐证其它定标方法可靠性的一种手段。
An absolute spectral radiometer was designed with a set of narrow-band filters, simple radiometers and silicon photodiode detectors. Accurately measure the spectral transmission function of the filter, calculate the field of view of the radiometer, and calibrate the absolute spectral responsivity of the detector to an absolute spectral radiometer to calibrate imaging spectroscopy and other optical remote sensors, Spectral irradiance lamps were compared to conventional methods of radiometric calibration. The results show that the radiation calibration method based on the detector is a way to improve the calibration precision of the optical remote sensor and is a means to prove the reliability of other calibration methods.
