Abstract

The operation of novelty filtering is demonstrated using a hybrid optical and digital system. Dynamic gratings are written in photorefractive Bi₁₂SiO₂₀ at 514 nm and read out at 633 nm. The transient properties of the readout beam are enhanced by the imposition of various extrinsic conditions. Temporal discrimination is further improved by digital thresholding. The overall system operates at TV frame rates.
