Optical Modeling and Performance Predictions.
This note presents some of the optical modeling work performed at JPL and at Goddard in support of the Laser Interferometer Space Antenna (LISA) effort. The end-to-end optical model will be used to generate a synthetic data stream. The simulation wil

BRDF at 3.39 microns was measured on silicon carbide and aluminum foam and on 401C10 black paint. BRDF of the black paint increases by a factor of 100 at glancing angle. BRDF of the foams increases by less than a factor of 10 at glancing angle.
