title: Bidirectional reflectance distribution function of the Infrared Astronomical Satellite solar-shield material.
abstract: The BRDF values of a special, striated gold sample at 10.6 and 118 microm were measured. For 118-microm radiation the values decrease from beta - beta(0) = 0.1 to 1 for both orientations, but the vertical orientation of stria always produces a higher value. At 10.6 microm the horizontal orientation produces BRDF values that start at approximately 10(-2) at 0.1 and decrease to approximately 5 x 10(-4) at 1. The vertical orientation generates curves that are considerably higher.
