Design and Analysis of a Stable Support Structure for a Near-Infrared Space-Borne Doppler Asymmetric Spatial Heterodyne Interferometer

Round 1

Reviewer 1 Report

The comments on the manuscript entitled "Design and Analysis of Stable Support Structure for a Near-infrared Space-borne Doppler Asymmetric Spatial Heterodyne Interferometer" By: Jian Sun, et al.:

1. The symbols used in the equations and in the text should be same; for example Δd and Δφ in Eq. (2) are written as ?? and ?? in the text.

2. Add a reference for Doppler velocity equation; Eq. (2).

3. It is recommended to mention the super-heterodyne interferometer in the literature; 10.1088/1361-6501/ab796f; 10.1049/iet-opt:20060107; 10.1016/j.optcom.2021.126753.

4. The optimization process of the parameters should be described in more details.

5. Please use more resolution figures for Figs. 7 and 14, the labels are not clear.

6. The manuscript needs to be carefully edited, e.g. "Table 5. Radom vibration test conditions." should be read "Table 5. Random vibration test conditions."

7. Is there any comparison between the maximum stress on the mechanical element in the present structure and previous works? please clarify.

8. The test conditions during the random vibration tests should be cleared and addressed.

9. The references are a bit old and there are 3 references for 2019-2023. Please add more recent works.

Reviewer 2 Report

 This paper discusses the Design and Analysis of a Stable Support Structure for a Near-Infrared Space-borne Doppler Asymmetric Spatial Heterodyne Interferometer. This paper describes the mathematical model of a flexible structure, where the parameters were optimized by requiring that the mechanical stress of the flexible structure and the shear stress at the bonding surface be less than the strength value. Before publishing, I have some major concerns

1. There is a lack of clarity in the abstract of the paper.

2. There are some minor grammar errors that need to be corrected.

3. The resolution of the figures needs to be improved.

4. Even though a table is required, the author should explain the Doppler Asymmetric Spatial Heterodyne Interferometer with an example.

5. In the manuscript, the author needs to describe the phase-retrieval algorithm in detail.

6. It is necessary for the author to compare his results with those reported in the literature.

7. The way the experimental results are presented is very poor and needs to be improved.

8. The conclusion part is very short; they discuss more results with evidence.

Need minor improvement

Reviewer 3 Report

With increasing spectral resolution of doppler Asymmetric Spatial Heterodyne (DASH) interferometer, the dimensions of the DASH increases as well. A stable and adiabatic support structure for a large-sized interferometer has become an urgent issue. The authors in this paper propose a novel and stable support structure based on mathematical modelling and parameter optimization for a near-infrared (NIR) DASH interferometer. The results are promising. However, I recommend the following minor changes in the paper to recommend the acceptance.   1-Although the authors have already detailed the literature review in section of the paper, I suggest to add a table in section 1 to summarizing the main contribution of the past works and the differences/ advantages of the proposed work.   2-Please consider latest studies 2015-2023 in literature review. Old references may please be omitted.   3-What is the basic difference between the DASH and HAPS? Can HAPS replace the DASH? I suggest to take help from these latest studies and update the bibliography by citing them.

4-The resolution and size of Fig. 1 and 4 is small. Please adjust them accordingly.   5-The resolution of plots of Fig. 7, 14, and 15c is low. Please improve the figures.
