Abstract

We demonstrate a new all-optical method of moire fringe analysis for the purpose of fast wavefront detection and correction of single ultrashort light pulses. The magnitude and sense of wavefront curvature is determined by fringe orientation. Single-shot fringe processing takes place at the Fourier plane of an imaging lens with an apodized slit as the transmission filter. The curvature (directional 2^nd derivative) of the wavefront shape is obtained as an image. Results imply the possibility of fast detection and correction of single pulses.
