Paper Abstract

For space object, intensity correlation is a high-resolution imaging method and it has favorable developing prospects. But the existing intensity correlation imaging focuses more on the second order intensity correlation combined with phase estimation. The absence of phase information brings out problems like twin images and limitations for low brightness and irregular object, which has trapped its progress in imaging. Instead of estimation, higher order or multi-detector correlation can directly measure the phase and avoid the complicated estimation process and extra error it introduces. Sensitive to measurement noise, the feasibility of multi-detector intensity correlation imaging for space object is discussed here. Also, the SNR of the measurement and reconstructed image quality is to be compared by adding the detectors and available improvements are proposed in this paper.
