Abstract

Because a joint transform correlator can be used as a general optical signal processor, complex-impulse-response implementations in the spatial domain are often requested. We introduce a position-encoding technique with which complex-valued references for the joint transform correlator can be obtained with an amplitude-modulated spatial light modulator. A proof-of-concept experiment is also provided.

摘要

由于联合变换相关器可作为通用光学信号处理器使用，因此常常需要在空间域中实现复脉冲响应。我们介绍了一种位置编码技术，利用该技术可通过幅度调制空间光调制器获得联合变换相关器的复值参考。本文还提供了一个概念验证实验。
