A three-dimensional (3-D) optical-scanning technique is proposed based on spatial optical phase code activation on an input beam. This code-multiplexed optical scanner (C-MOS) relies on holographically stored 3-D beam-forming information. Proof-of-concept C-MOS experimental results by use of a photorefractive crystal as a holographic medium generates eight beams representing a basic 3-D voxel element generated via a binary-code matrix of the Hadamard type. The experiment demonstrates the C-MOS features of no moving parts, beam-forming flexibility, and large centimeter-size apertures. A novel application of the C-MOS as an optical security lock is highlighted.
提出了一种基于输入光束空间光学相位码激活的三维（3-D）光学扫描技术。这种码分复用光学扫描仪（C-MOS）依赖于全息存储的三维波束形成信息。使用光折变晶体作为全息介质的概念验证C-MOS实验结果产生了八束光，代表了通过哈达玛型二进制码矩阵生成的基本三维体素元素。该实验展示了C-MOS无移动部件、波束形成灵活性和厘米级大孔径的特点。重点介绍了C-MOS作为光学安全锁的一种新应用。
