Abstract: The responsivity of optical detectors to light can vary when the light illuminates different areas of the detector. A scanning system for measuring the uniformity of the responsivity of optical detectors, and methods of quantifying the degree of uniformity are described here. Surface plots and topographical maps of the measured responsivity are presented along with a statistical treatment. Sampling theorem restrictions affecting the accuracy of the results are described. Scans of actual detectors are included to show the range of uniformity possible.
