摘要

The quantum imaging (ghost) has attracted many attention in recent years. In the ghost imaging scheme, the object information is captured by the "bucket" detector which has no spatial information. In practical scheme, the CCD array or the APD are utilized as the "bucket" detector, but the saturation effect of the detector may exist due to the limited sampling depth of the detector. The two methods are presented to reduce the effect of the saturation for different "bucket" detectors. The method for CCD array is based on the statistic principle of ghost imaging, and the other is based on the compressed sensing. After that, we compare the difference between the ghost imaging and compressed sensing in the low light level condition.
