Abstract : The three major components of the Contrast Attenuator were studied in detail. These are the dichoric filter arrangement which was also breadboarded, the illumination source and optics, and the neutral density wedge system. A study of the Spatial Frequency Analyzer was made and a breadboard of the system set up. Some photographs illustrating spatial filtering were taken. (Author)
