Real-time edge enhancement of femtosecond time-domain images by use of photorefractive quantum wells

Abstract

Dynamic holograms written in a photorefractive multiple quantum well placed inside a Fourier femtosecond pulse shaper convert a space-domain image into the time domain. We demonstrate that edge-enhancement processing of the time-domain image can be performed by controlling hologram-writing intensities.
