“…Требования к спектрометру значительно возрастают, когда необходимо регистрировать спектры источников слабого свечения в широком диапазоне длин волн. Сегодня, в связи с развитием и прогрессом вычислительной техники, появлением более чувствительных фотоприемников открываются пути дальнейшего совершенствования спектральной техники [1][2][3][4][5][6][7].…”

A novel tempo-spatially mixed modulation imaging Fourier transform spectrometer based on a stepped micro-mirror has the advantages of high throughput, compactness, and stability. In this paper, we present a method of image- and spectrum-processing and performance evaluation, which is utilized to obtain a high-quality reconstructed image without stitching gaps and a reconstructed spectrum with significantly reduced noise and side-lobe oscillation. A theoretical model of instrument line shape and signal-to-noise ratio is established to verify the effectiveness of non-uniformity sampling correction and spectral resolution enhancement. Meanwhile, the performance of the instrument was evaluated combined with experimental results.
