摘要：
Optical processing via high-pass filtering is a well-established means of enhancing image contrast. However, this procedure is energetically inefficient, because the power associated with the low-spatial-frequency components of the image is ordinarily discarded. We demonstrate a means of performing contrast enhancement in an energy efficient manner, by recycling the optical power ordinarily discarded using photorefractive two-beam coupling in barium titanate.
