The BLOL can be used for passive measurement of water leaving radiance L w  and active measurement of the diffuse attenuation coefficient k(532 nm) and chlorophyll a concentration C.

Solar ultraviolet(UV) spectral monitor(SUSM) is a compact,high-precision satellite-borne spectroradiometer designed to measure the solar ultraviolet-spectral irradiance and the solar backscatter vltraviolet-spectral radiance from the atmosphere under two different work modes.

The linear dimming system makes the radiance of the sphere exit portal decrease pro rata 10% from t.

In order to acquire precision pushbroom images at different radiance of the earth object, and according to the working environment of space camera.

Study on inversion of radiometric parameters of ground objects (such as radiance and reflectivity) was little, because the band number and bandwidth of sensor restrict the application in the fields of radiometric calibration and quantification of remote sensing.

In this article, the 6S atmospheric model with a digital elevation model(DEM) is used to calculate direct and diffuse illumination on horizontal surface, and the illumination is then transformed to sloping surface, meanwhile, 6S model can perform atmospheric correction over the imagery and output the radiance and reflectance at the bottom of atmos.

A simple but accurate model of the upwelling solar radiance is of great significance for the atmospheric correction in the case of satellite remote sensing of surface parameters.

Prediction of radiant brightness values of deuterium lamps using B P neural network;

In order to describe the non compatibility among the evaluation results of single indexes of optical radiant brightness,the matter element transformation was used for transforing the non compatible problem into compatible problem.
