Pagination or Media Count:
The need for a light deflector has become more pressing since the advent of lasers. Such applications as optical memories, a line scan illuminator, or search and track optical radar require a beam steering device. Properties such as high resolution, wide angle deflection - preferably in two dimensions - , high scan rates, high random access rates, and the ability to withstand extreme environments often encountered in tactical situations are sought. The magnetic stripe domain deflector offers important advantages in these respects. The purpose of this contract was to evaluate the prospects of a stripe domain light deflector using such materials as mismuth-doped yttrium iron garnet Bi YIG, iron-chromium trihalides, and iron cobalt nickel borates for the green 5145 A Argon line.
