Abstract :
Summary form only given. Electrically controlled spectral filters are based on the technique of Electric Field Multiplexing (EFM) of volume holograms. In this report we describe the optimal experimental configuration for recording and restoration of these filters in photorefractive LiNbO/sub 3/ and present a comparison of theoretical and experimental data obtained in studies of reflectivity as a function of external electric field.
