We present a new type of optical convolver / optical correlator capable of encoding higher orders. The technique is based on obtaining higher powers of a properly designed hologram. This can be obtained in two ways. First, we can recalculate higher orders of the amplitude and phase hologram in a standard spatial light modulator (SLM). More easily, we can utilize a phase-only hologram and exploit the properties of an SLM with extended phase modulation range. Experimental results agree with theory in both cases.

使用具有扩展相位范围的空间光调制器的多阶相关和卷积

我们提出了一种能够编码更高阶的新型光学卷积器/光学相关器。该技术基于获得适当设计的全息图的更高功率。这可以通过两种方式获得。首先，我们可以在标准空间光调制器 (SLM) 中重新计算更高阶的幅度和相位全息图。更容易的是，我们可以利用仅相位全息图并利用具有扩展相位调制范围的 SLM 的特性。在这两种情况下，实验结果都与理论一致。
