摘要

关联成像近年来成为光学成像领域的研究热点, 光学相控阵集成度高、成本低和调制速率高等优点非常适合应用于关联成像. 本文使用二维独立相位控制的光学相控阵, 研究了光学相控阵产生的周期性赝热光场赋予关联成像的新特性: 分别在暗室、有相位干扰和有热光噪声的条件下基于双周期光场进行了无分束器的关联成像实验; 并利用光学相控阵双周期光场实现了图像拼接. 研究结果对于促进关联成像技术的进步、拓展光学相控阵的应用有重要的意义.

Abstract

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.
