Paper Abstract

The moderate resolution imaging spectroradiometer (MODIS) will be one of the primary instruments observing the earth on the Earth Observing System (EOS) scheduled for launch at the end of this decade. Its 36 spectral bands ranging from 0.4 to 14.4 microns will image the entire earth. The radiometric requirements are such that the contributions to the optical point spread function from optical ghosts, scattered light and cross-talk in the very small spectral filters, located near the focal planes, must be characterized very well and kept to a minimum. This paper describes a series of Monte Carlo simulations of the propagation of light through the optics in order to determine the extent of the ghosting and scattered light. These results are also compared with experimental data.
