We propose a new class of aperture-coded spectrometer that is optimized for the spectral characterization of diffuse sources. The instrument achieves high throughput and high spectral resolution by replacing the slit of conventional dispersive spectrometers with a more complicated spatial filter. We develop a general mathematical framework for deriving the required aperture codes and discuss several appealing code families. Experimental results validate the performance of the instrument.
我们提出了一种新型的孔径编码光谱仪，它针对漫射源的光谱特征进行了优化。该仪器通过用更复杂的空间滤波器取代传统色散光谱仪的狭缝，实现了高吞吐量和高光谱分辨率。我们开发了一个通用的数学框架来推导所需的孔径编码，并讨论了几个有吸引力的编码系列。实验结果验证了该仪器的性能。
