Paper Abstract

The ability of optical seeker/sensor systems to acquire, discriminate, and lock on to their targets is essential to the success of all interceptor systems. A telescope primary mirror is highly vulnerable to x-ray exposure, which may result in increased scatter as well as permanent and/or transient distortion. Interceptor target discrimination and tracking is thus compromised. We have fielded several experiments to examine the effects of nuclear radiation on a variety of mirror samples representing those technologies which might be applicable for an optical sensor/seeker system. Mirror deformation and scatter measurements were performed in real-time, providing dynamic response and recovery data. Post-test measurements included scatter, reflectance, and permanent distortion as well as microscopic examination of the mirror surfaces. Results from these experiments are presented along with comparisons to analytical models.
