Influence of the Angular and Temporal Spectrum of a Pseudo-Thermal Light Source on the Quality of Ghost Imaging

In the report, we will consider the classical ghost imaging using a pseudo-thermal light source. We demonstrate that width the angular spectrum of the pseudo-thermal source determines the resolution of ghost imaging optical system. We found that the temporal coherence length determined by velocity of shift of speckle patterns. Partial temporal (between measurements) correlation of speckle patterns of a pseudo-thermal source degrades the quality of a ghost image.
