We describe a parallel optical processor, based on a lenslet array, that provides general linear two-dimensional transformations using noncoherent light. Such a processor could become useful in image- and signal-processing applications in which the throughput requirements cannot be adequately satisfied by state-of-the-art digital processors. Experimental results that illustrate the feasibility of the processor by demonstrating its use in parallel optical computation of the two-dimensional Walsh-Hadamard transformation are presented.
我们描述了一种基于微透镜阵列的并行光学处理器，它使用非相干光提供一般的线性二维变换。这种处理器在图像和信号处理应用中可能会很有用，因为在这些应用中，现有的数字处理器无法充分满足吞吐量要求。本文给出了实验结果，通过展示其在二维沃尔什 - 哈达玛变换的并行光学计算中的应用，说明了该处理器的可行性。
