Abstract : The overall objective of this project was to evaluate the Peerless flash-ranging set, AN/TVS1(XE-3), prior to its acceptance by the United States Army Signal Research and Development Laboratory (ASRDL). The specific objectives were to determine the operational capability of two types of automatic shutter- activating units and to compile data on shutter speeds and filter values at different ranges from point of burst of various low-yield nuclear devices. The project participated in eight detonations at the Nevada Test Site (NTS). Consistent, reliable operation of the equipment tested was obtained at 18 miles from burst. This distance was the maximum lineof-sight range available for a suitable observation point. Although both types of automatic shutter-activating units performed equally well under conditions of high visibility such as existed during the test participations, the modified version was considered most applicable. Camera settings were kept constant. No recommendation for an overall optimum filtering can be made because samples included only low-yield detonations and cannot be correlated to higher yields, varying ranges, and changing ambient light conditions.
