Abstract : The feasibility of a reversibly frostible window for flashblindness protection was investigated. Fluids were studied which frost when electrically charged by either corona or glow discharge. Optical and temporal performance was measured for several such fluids. Under the conditions employed, five frost layers in series were enough to bring about an increase in apparent density in the incident direction to the requisite level of 3. Several of the experimental fluids frosted within the requisite 150 microsec., but they did not do so consistently, primarily because of the capriciousness of the gaseous discharge method of injecting charges into a fluid surface. Eventual success of the frostible window concept hinges on the development of an efficient charging technique. (Author)
