Photorefractive integrator characterization.
We describe the recent results of our efforts to characterize a photorefractive crystal to be used as a time-integrating device in an optically implemented null-steering adaptive processor for phased-array radar. We review frequency response data for the Bi(12)SiO(20) crystals, measured with an acousto-optic apparatus, and we present measured dynamic range data for the candidate Bi(12)SiO(20) crystals.
