Noise-robust computational ghost imaging with pink noise speckle patterns

We propose a computational ghost imaging (CGI) scheme using customized pink noise speckle pattern illumination. By modulating the power spectrum distribution of speckles, we generate patterns with significant positive spatial intensity fluctuation correlation. experimentally reconstruct images our synthesized in presence variety sources and distortion show it is robust to environment. The results are compared use standard white patterns. that method gives much better image qualities under different types than traditional way. proposed promises potential applications underwater, dynamic, moving target CGI.
