Abstract

Most modern imaging systems function in a parallel acquisition scheme.1, 2 For example, the ubiquitous digital optical cameras of today employ arrays of pixels that each detect local light intensity, and simultaneously generate proportional electrical signals to construct an image. However, assembling the large quantities of detectors that are required for parallel imaging is not always feasible for other frequencies of light. In particular, there is a

超材料调制器使新的太赫兹成像技术成为可能
大多数现代成像系统都采用并行采集方案。例如,今天无处不在的数字光学相机采用像素阵列,每个像素阵列检测局部光强度,同时产生成比例的电信号来构建图像。然而,组装平行成像所需的大量探测器对于其他频率的光并不总是可行的。特别地,有一个
