| Popis: | We demonstrate a novel tempo-spatial mixed-modulation Fourier-transform infrared imaging spectrometer. The static interference channel based on a stepped micro-mirror contributes a compact system with high stability. The instrument functions in two spectral bands ranging between 3.7– $4.8~\mu \text{m}$ and 7.7–9.3 $\mu \text{m}$ , and the spectral resolution of the dual-interference channels achieves 51.5 and 4.1 cm−1, respectively. The instantaneous field of view is 0.15 mrad, and the working F/1.93 enables high optical throughput. The optical design and tolerance are presented with experimental investigation results, showing attractive potential in remote sensing application. |
