Investigation of PZT Materials for Reliable Piezostack Deformable Mirror with Modular Design

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This paper describes a piezoelectric variant, with a fairly large amount of characterization data provided, but needing substantial revision in terms of presentation.   

- More detail is needed on how the mateiral is created.  Even though this is leaning heavily on prior publications, there is not enough detail within this work to understand the contents or fabrication approach behind the key material.  

- most of the material in section 2.1 is standard, and does not need to be covered in the current level of details (the figures, in particular, add no new understanding).

 

- The test results are very important, but should be reformatted into a more conventional archival style; they appear to be screenshots in the current work

- It is critical to compare the properties of the proposed material, either at the single element or stack level, to existing materials, for benchmarking of performance.

Comments on the Quality of English Language

The English language need substantial editing, particularly in the the Abstract and Introduction.

Thank you very much for your review and constructive comments on submitted manuscript. These comments are valuable and helpful for improving the quality of the manuscript.

"More detail is needed on how the mateiral is created.  Even though this is leaning heavily on prior publications, there is not enough detail within this work to understand the contents or fabrication approach behind the key material."

Thank you for your suggestion. We added more details in the section 2.2 with an extensive desciption of the manufacturing process of the material.   

"most of the material in section 2.1 is standard, and does not need to be covered in the current level of details (the figures, in particular, add no new understanding)"

You are right. This part has no new understanding or innovative points. It was added for readers who don't have much experience in this area to provide more extensive comprehension of this work 

'The test results are very important, but should be reformatted into a more conventional archival style; they appear to be screenshots in the current work'

Thank you very much for your comment. We have a raw data for plots that you pointed for reformatting. Unfortunately, they may be slightly in unpresentable form for readers.

'It is critical to compare the properties of the proposed material, either at the single element or stack level, to existing materials, for benchmarking of performance.'

Thank you very much for your suggestion. We added information about manufacturers of the piezoceramic materials with comparison of their key parameters.

Reviewer 2 Report

Comments and Suggestions for Authors

Thank you for the authors providing a useful study on PZT material. Based on PZT ceramic and modular design, a high performance PKP-12 was produced. Some minor concerns below were proposed.

(1)   A comparison table of PZT material and PKP-12 should be given to shown the superiority of the proposed KPK-12.

(2)   Line 231 The label of Table 2 was missing.

Thank you very much for your comments. They are very important to improve the quality of the submitted paper.

'A comparison table of PZT material and PKP-12 should be given to shown the superiority of the proposed KPK-12.'

We added comparison of the manufactured material with analysis of key parameters from other piezoceramic manufacturers. You can find it in Table 2. 

'Line 231 The label of Table 2 was missing.'

Thank you very much for careful reading. We added the heading for Table 3 in new version of the manuscript.

Round 2

Reviewer 1 Report

Comments and Suggestions for Authors

This work topic is interesting and the experimental results could be useful, but the presentation of results is still not very well matched to journal publication.  The space taken up by the basic piezoelectric principles and the flow chart of processing is unnecessary, and could be much more compact.  Meanwhile, the results plots really need to be transferred to a white background for better visibility and consistence with more common graphical styles of the journal.

Comments on the Quality of English Language

The language is fine but often more wordy than necessary. Not a key concern, but could be made more concise.

Author Response

Thank you very much for your comments. We reduced  description of basic principles of piezotechnique in the introduction part. Moreover, we changed the presentation of the graphical materials to improve readability of them. Also, we checked the English language quality and add some points about deformable mirror performance.
