本项目提出一种新型的无透镜微光学平面集成相关器。采用折反式光路设计和微光学方法将两个分别用于输入与光学滤波的空间光调制器和反射镜等物理器件集成在同一平面上，用微光学方法将虚拟数字Fourier微透镜和匹配滤波器加载到空间光调制器以实现光学相关。这种紧凑的平面集成结构设计，无需物理的Fourier透镜，能够有效地减小系统体积和负荷、提高识别精度和可靠性、降低制作成本。无透镜平面集成微光学相关器技术，在光电信息实时处理、光计算、模式识别、机器视觉、海量信息检索和人工智能等领域有重要而广泛的应用前景。

A novel type of lensless plan-integrated micro-optical correlator (LPMOC) is proposed. The LPMOC is a single compact device by integrating both two spatial light modulators and mirrors on the same substrate. The light path of refraction-reflection and virtual digital microlens are adopted inside the LPMOC for the purpose of reducing volume and enhancing optical properties. The LPMOC may have wide and important applications, such as on-site photoelectric information processing, optical computing, pattern recognization, machine vision, mass information retrieval，etc.
