Incoming radiance

WebThe standard convention is to parameterize the incoming radiance L i at ~xwith the direction from the receiver ~xto the source ~x0. When using this convention, the incoming radiance is defined on a ray pointing in the direction opposite to the direction of light propagation. It is also useful to introduce notation for the two-point radiance WebNov 15, 2013 · For on-orbit calibration of the Beijing-1 multispectral imagers (Beijing-1/MS), a field calibration campaign was performed at the Dunhuang calibration site during September and October of 2008.
