Research abstract
Accuwave Corporation will demonstrate an optical limiter for sensor protection using two-beam coupling in a photorefrac-tive material to attenuate coherent input light while leaving incoherent light unaffected. Methods for decreasing response time in BaTiO3, SBN, and similar materials will be investigated. A laboratory breadboard telescope system with an integrated limiting element will be demonstrated and characterized to determine total transmitted energy and transmitted signal distortion. Potential commercial applications include personnel laser protection devices and LIDAR receiver filters.
