The effect of spatial transverse coherence property of a thermal source on Ghost imaging and Ghost imaging via compressive sampling

摘要

Both ghost imaging (GI) and ghost imaging via compressive sampling (GICS) cannonlocally image an object. We report the influence of spatial transversecoherence property of a thermal source on GI and GICS and show that, using thesame acquisition numbers, the signal-to-noise ratio (SNR) of images recoveredby GI will be reduced while the quality of reconstructed images will beenhanced for GICS as the spatial transverse coherence lengths located on theobject plane are decreased. Differences between GI and GICS, methods to furtherimprove the quality and image extraction efficiency of GICS, and its potentialapplications are also discussed.
