Abstract : An optical tool has been developed for aligning a beam of parallel light with respect to a reference axis. The tool was designed specifically for use with the yawsonde calibration system at BRL, where the requirement was to align the light beam so that it was at an angle of 90 degrees plus or minus .017 degrees with respect to the reference axis. However, the principles and techniques can be adapted to other applications. This report describes the optical tool and presents an alignment scheme for using it. (Author)
