SWIR AOTF Imaging Spectrometer Based on Single-pixel Imaging
Round 1
Reviewer 1 Report
The paper is well structured and well written. The desriptions, analysis and conclusions are clear. The references formatting should be unified according to the MDPI's requirements.
If the authors write "At present, the AOTF spectrometer is applied to many fields, such as..."
I would expect some citations of the latest papers, while the newest one that was cited is from 2014.

Reviewer 2 Report
Dear Authors,
In this paper, the authors combined compressed sensing and acousto-optic tunable filter (AOTF) technique to achieve single pixel imaging in the near IR range.
The paper is well organized and the results are sound. I recommend it for publication.
