Comments and Suggestions for Authors

Optical frequency domain reflectometry (OFDR) is highlighted as a promising and non-destructive technique within the study. This advanced optical method offers significant potential for various applications, particularly in the fields of materials science and nanotechnology. However, to make the content more accessible to readers who may not be familiar with this family of optical techniques, it would be beneficial to include a discussion of the limitations and advantages of OFDR. Such a discussion would provide a more balanced understanding of the technique, allowing readers to better appreciate its strengths and the contexts in which it is most effective.

Additionally, the manuscript would benefit from a more detailed exploration of the scenarios in which cracks and defects are likely to occur. This could include a discussion of the types of materials and environmental conditions that are prone to crack formation, as well as the specific stages in the material lifecycle where such issues might arise. This added detail would help to contextualize the relevance of OFDR and other techniques in detecting and analyzing these critical defects.

Moreover, I suggest considering the inclusion of videos in the supplementary material. Visual demonstrations of the OFDR technique in action, as well as examples of crack detection, would significantly enhance the reader’s understanding. Videos can effectively illustrate complex processes and results, providing a dynamic complement to the static figures and text in the manuscript. This addition would be particularly valuable for engaging a broader audience, including those less familiar with the technical aspects of the research.
