Özet

Image zero frequency is partially depleted by two-wave mixing in a photorefractive BaTiO3 crystal. This is done by coupling a small-size reference beam with the central part of the spectrum. The main advantage of this method over the well known selective amplification technique is the limitation of the beam-fanning and the high speed of filtering. The application of high-pass filtering based on the photorefractive effect to particle field holography is considered.
