In this study, a scheme is constructed based on multi-channel parallel detection to improve the quality of photon-counting correlated imaging. Further, the imaging performance of the constructed scheme is analyzed and verified using numerical simulation. Subsequently, the influences of the detection channel number, the average level of the echo signal photon, and the sparsity of the irradiation speckle field on the imaging quality are discussed. The numerical simulation results show that the imaging quality is positively correlated with the detection channel numbers in this scheme. The imaging quality is first improved and then degraded with an increase in the average level of the echo signal photon and the sparsity of the irradiation speckle field.
