Abstract

Speckle patterns are random patterns that can commonly be observed when coherent light interacts with an optically rough scattering surface or medium. One important metric in describing the speckle pattern is the speckle size, as it affects the resolution of some imaging techniques that make use of speckle. As such, the control of speckle size is an essential concern for most techniques. This work aims to investigate the feasibility of using phase modulation at the Fourier plane in order to control the behavior of the speckle size of a speckle pattern.
