Ghost Imaging with XY Phase Series Space Light Modulator

Ghost imaging has emerged a decade ago as a new imaging technique. Its feature is the image will appear on the optical path, which never passes through the object actually. In this paper, we will give an overview of quantum imaging, include the experiments with two-photon entanglement state source generated by spontaneous parametric down conversion, as well as with pseudo-thermal light. Then we will show our ghost imaging experiment scheme with the pseudo-thermal light source. We obtain the pseudo-thermal source by using a XY Phase Series Spatial Light Modulator (supplied by BNS company) to modulate the laser light. This spatial light modulator changes the phase of the output light field by controlling the loading element on every pixel.
