The hybrid optoelectronic correlator (HOC) combines optical and electronic signal processing to achieve the same functionality as traditional optical correlators but without the need for dynamic materials. Here we propose and demonstrate the integration of a PQ:PMMA holographic memory device (HMD) into the HOC as a high-speed all-optical database for reference images. Using a PQ:PMMA HMD for one of the inputs eliminates one of the key speed limitations in the HOC. The observed correlation signal agrees with simulations but highlights the need for high quality holographic substrates in this application.
混合光电相关器(HOC)将光学和电子信号处理相结合,以实现与传统光学相关器相同的功能,但无需动态材料。在此,我们提出并展示了将PQ:PMMA全息存储器件(HMD)集成到HOC中,作为用于参考图像的高速全光数据库。将PQ:PMMA HMD用于其中一个输入消除了HOC中的一个关键速度限制。观察到的相关信号与模拟结果相符,但突出了在此应用中对高质量全息基板的需求。
