Abstract: A vidicon camera and a secondary electron conduction camera were compared on the basis of noise, modulation transfer function at high and low contrasts, sensitivity, response to scene motion and response to bright sources within the field of view. The tests were conducted with underwater resolution charts of 90% and 40% contrast. Since the cameras had different fields of view and video bandwidths, all measurements were made with a 5-MHz cutoff filter with the camera located to give the proper geometrical relationship with the special underwater resolution charts used. The results of these tests led to the conclusion that the vidicon is superior at high scene contrast and brightness, while the SEC camera tube is better at low scene contrast and brightness levels.
