Inhaltsangabe:
- Ghost imaging and differential ghost imaging are well-known imaging techniques based on the use of both classical and quantum correlated states of light. Since the existence of correlations has been shown to be the main resource to implement ghost imaging and differential ghost-imaging protocols, here we analyze the advantages and disadvantages of using two different kinds of superthermal states of light, which are more correlated than the typically employed thermal states. To make a fair comparison, we calculate the contrast (C) and the signal-to-noise ratio (SNR) of the reconstruct image. While the larger values of C suggest the usefulness of these superthermal states, the values of SNR do not improve by increasing the intensity fluctuations of light. On the contrary, they are the same as those exhibited by thermal light.
