本文描述了一种基于压缩感知概念的单次光谱成像方法。系统设计的主要特征是两个色散元件，相对布置并围绕二进制值孔径码。与光谱滤波的薄膜方法相比，这种结构导致易于控制的、空间变化的、具有窄特征的光谱滤波器功能。通过这些滤波器对输入场景的测量相当于谱域中的投影测量，因此可以用最近由许多组开发的压缩感知框架来处理。我们提出了一个重建框架，并证明其应用程序的实验数据。(c)2007年，美国光学学会。
This paper describes a single-shot spectral imaging approach based on the concept of compressive sensing. The primary features of the system design are two dispersive elements, arranged in opposition and surrounding a binary-valued aperture code. In contrast to thin-film approaches to spectral filtering, this structure results in easily-controllable, spatially-varying, spectral filter functions with narrow features. Measurement of the input scene through these filters is equivalent to projective measurement in the spectral domain, and hence can be treated with the compressive sensing frameworks recently developed by a number of groups. We present a reconstruction framework and demonstrate its application to experimental data. (c) 2007 Optical Society of America.
