title: Random gratings as correlator sensors.
abstract: A random grating is a periodic structure whose unit cell has random variations. Hence, its autocorrelation function shows high periodic peaks, which may be useful for implementing holographic sensors for in-plane lateral displacements or phase-gradient detection. We report what we believe to be the first experimental verification of this finding.
