Correlated imaging, or ghost imaging, has aroused the interest of researchers in recent years. Optical phased array (OPA) as a high-integration, low-cost, and high-speed light illuminating device is suitable for application in correlated imaging. Here we use a two-dimensional 4 × 4 silicon integrated OPA in which each channel has an independently tunable phase shifter. In this work, the new features of correlated imaging given by periodic pseudo-thermal light field of OPA are demonstrated. The correlated imaging with biperiodic light field of OPA under different conditions including darkroom, thermal noise and phase perturbation without splitter is reported; the image stitching based on biperiodic light field of OPA is also presented. This work is of significance in promoting the progress of imaging technology and expanding the application of OPA.
