Abstract
A classical coincidence imaging or ghost imaging experiment is carried out in a two-photoncounting regime using a pseudo-thermal incoherent light source. The effect of thetransverse size and transverse coherence width of the source on the visibility andthe resolution of the reconstructed ghost image is studied. It is observed thatby increasing the transverse size of the source, the resolution (quality) of thereconstructed image improves, while the visibility reduces. On the other hand, as thecoherence width of the source increases, the visibility of the image increases but theresolution becomes poor. The effect of object characteristics on the visibility ofthe ghost image is also studied and it is found that by increasing the number oftransparent features and the surface size of the object, the visibility of the imagedecreases. These experimental results validate the theoretical results published sofar.
