Abstract
The Remote Sensing Group of the Optical Science Center at the University of Arizona has developed a four-band, multi-spectral, wide-angle, imaging radiometer for the retrieval of the bi-directional reflectance distribution function (BRDF) for vicarious calibration applications. This article discusses the results of laboratory characterization of the system to determine linearity of the detector, point spread function (PSF) and polarization effects. The results indicate that BRDF data from the camera system is accurate to better than 1% at field angles of less than 20 degrees, and to 3% out to 70 degrees.
