A single-pixel camera is composed of optical coding masks, a photo detector, and a computational decoder as the important feature that it requires no image sensor for imaging, and therefore has very simple optical and electrical architectures. The optical coding masks, the implementation of which is a novel point of our research, are composed of holes on a substrate and are arranged on the circumference of a disk to allow mask switching by rotation of the disk. The main features are a simple structure that brings low cost in optics and electronics, no path difference in the mask, and no wavelength dependence except for a dependence on air for wideband spectral imaging. Spectral imaging of a sample composed of color films is demonstrated, and the accuracy of the proposed system is evaluated to make the most of the features.

带孔阵列盘的单像素相机

单像素相机由光学编码掩模，光电探测器和计算解码器组成，其重要特征是不需要图像传感器进行成像，因此具有非常简单的光学和电气架构。光学编码掩模的实现是我们研究的一个新点，它由基板上的孔组成，并排列在磁盘的圆周上，以允许通过磁盘旋转来切换掩模。其主要特点是结构简单，不仅降低了光学和电子设备的成本，而且掩模的光程差也没有，除了宽带光谱成像对空气的依赖以外，对波长也没有依赖性。演示了由彩色胶片组成的样品的光谱成像，并评估了所提出系统的准确性，以充分利用这些功能。
