Comments and Suggestions for Authors

This paper designed an imaging optical system with an infrared band from 3–5 μm and a field of view of 1.7°×1.7° and studied Stray light sources are analyzed, and effects of external stray light on imaging quality and internal stray light on the interference effect. This is an interesting research paper. There are some suggestions for revision.

1)   The motivation is not clear. Please specify the importance of the proposed solution.

2)   Please highlight the novelty of the proposed solution in introduction.

3)   There was a lack of discussion of the limitations of the proposed methodology and the room for improvement. In the concluding part, the limitations of the proposed methodology should be discussed, and possible directions for improvement and future work should be proposed.

4)   Why do you use Tracepro software for simulation? It is suggested to give a statement of its superiority and appropriateness.

5)   The paper provides insight into the discussion of the effect of stray light on the interference fringes of Michelson interferometers. However, the paper can analyze this phenomenon from a deeper perspective, including potential mitigation strategies or the practical implications of interferometer design in different applications.

6)   What are the advantages of the Cassegrain coaxial folding transmission structure used in the front telescope system described in this paper compared with traditional transmission systems? How does it achieve high-quality imaging and compact size?

7)   What do solid angle reflectors SAM1 and SAM2 do, and how do they function?

8)   How can the innovative design of the optical system mentioned in the paper be applied to the development of military and civilian spectrometers? Is this application limited or required by a specific application area?

9)   The overall technical depth is a little bit low. Please give more technical details.

10)          The experimental results are not convincing. Please compare the proposed solution with more recently published solutions.
