Abstract:
The design, construction and details of operation of an instrument for measuring Bidirectional Scattering Distribution Functions (BSDF) {i.e., Bidirectional Reflection Distribution Functions (BRDF) and Bidirectional Transmission Distribution Functions (BTDF)} at four wavelengths from the visible to the far infrared (FIR) are presented. Hardware, software, theory, calibration, accuracy and performance are all addressed. The four major interacting subsystems--optical, electronic, mechanical and computer--are discussed in various degrees of detail. A BASIC language control program for running the system via the Z-80 microprocessor is included in the appendix. The origin of BRDF is traced, and a brief theoretical summary examines it from both a physical optics and a radiometric point of view. Modeling is performed to determine the effect of large radiometer collecting apertures on accuracy. Dynamic range and resolution are determined from experimental and theoretical considerations. Finally, new measurements of Martin Black at 118.8 (mu)m are presented along with measurements at 0.6328, 3.39 and 10.6 (mu)m. The FIR BRDF measurements covered 6 orders of magnitude and values as low as 6 x 10('-4) sr('-1) have been recorded.
