Abstract : Two concepts of phototropic systems application are presented in this report. These concepts, when considered individually or in combination, make possible the development of improved, directly or indirectly actuated, phototropic, ophthalmic, nuclear flash-protective devices. By the application of a phototropic filter at the focal plane of an optical system, the attenuation of the phototropic response due to distance is minimized. Using a renewable fluid filter, a concept is presented which offers the opportunity to use the more sensitive irreversible phototropic systems while still providing reversible characteristics. The operating characteristics of these concepts are presented along with some derived theoretical relationships. (Author)
