利用光学记忆效应以及散斑图的空间相关性和整体相关性之间的等价性，我们提出了一种新的单像素摄像机概念。它允许无透镜显微光谱和深度分辨成像与空间光调制器显示伪随机散射阵列。由于图像检索是基于相关计算，这个概念被证明是相当强大的噪声。
Exploiting the optical memory effect and the equivalency between the spatial and the ensemble cross-correlation of speckle patterns, we developed a new single-pixel camera concept. It allows lensless microscopic spectrally and depth resolved imaging with spatial light modulators displaying pseudorandom scattering arrays. Since the image retrieval is based on correlation calculations, the concept proves to be quite robust to noise.
