Paper Abstract

The conventional speckle contrast measures only speckle severity, and is unable to characterize granularity and anisotropy in displayed images, which are easily picked up by human observers. Here, we propose a comprehensive method based on the power spectral density which allows the simultaneous measurement of three components of laser speckle-severity, granularity and anisotropy-as a superior way to evaluate both speckle and speckle reduction techniques.
