Abstract

The dependence of laser speckle power spectral density on the autocorrelation of the aperture pupil function was verified using a charge injection device (CID) camera. Speckle patterns acquired by the CID array were processed to compute the power spectral density (PSD). Three aperture shapes were studied. There was good agreement between the theoretical and experimental power spectral density shapes, and the cutoff frequencies agreed within five percent error.
