We design, implement, and test a multichannel photorefractive optical joint transform correlator that is capable of performing sorting tasks for robotic applications. The use of mini-YAG lasers and liquid-crystal spatial light modulators, in conjunction with updatable holographic BSO crystals, results in a compact correlator (600 mm x 300 mm x 300 mm) with real-time capabilities (100-ms recognition speed). Flexibility is a built-in feature, and correlation is demonstrated for various applications. Electronic and optical preprocessing and postprocessing for improving demonstrator performances are also discussed.
我们设计、实现并测试了一种多通道光折变光学联合变换相关器，它能够执行机器人应用中的分类任务。使用小型YAG激光器和液晶空间光调制器，结合可更新的全息BSO晶体，得到了一个紧凑的相关器（600毫米×300毫米×300毫米），具有实时能力（100毫秒识别速度）。灵活性是其内置特性，并且针对各种应用展示了相关性。还讨论了用于提高演示器性能的电子和光学预处理及后处理。
