Abstract
Attempting to determine the quality and uniformity of a smooth surface from examination of BRDF raster scans can be a risky business as evidenced by studies of commercially grown and polished GaAs wafers. To demonstrate this, raster scan variations with respect to wafer orientation are presented along with a method for analyzing these variations without the need for making multiple raster scans. Some possible sources of the orientational variations are indicated by the data.
