Backlight Imaging Based on Laser-Gated Technology
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis paper presents an innovative approach to backlight imaging based on Active Illumination Laser Gated Imaging Technology (AILGIT). The authors have effectively explored AILGIT's application potential in challenging backlight conditions, providing quantitative analysis and experimental validation. The content is both original and well-structured, and the study's findings are substantiated by comprehensive data. Overall, the paper is acceptable, with a few minor revisions suggested below to further enhance clarity and scientific rigor.
1. Terminology Consistency
The acronym "AILGIT" is well-defined early in the paper, but there are some inconsistencies in terminology in sections such as the experiments and discussion. For example, both "Active Illumination Laser Gated Imaging Technology" and "Laser Gated Imaging" appear interchangeably. Consistent terminology throughout would improve coherence.
2. Figure and Data Annotations
Figures 2 and 3 are valuable for illustrating experimental results under backlight conditions. However, the figure legends and annotations are somewhat brief. I recommend providing additional experimental setup details, such as laser wavelength and pulse duration, in the figure captions to assist readers in better understanding the conditions of the experiment.
3. References Update and Completeness
Some references, such as those related to previous work on backlight imaging may be slightly outdated. Including recent references would better reflect current advancements and further substantiate the background research, ensuring the paper is comprehensive and aligned with the latest developments.
Conclusion
Overall, this paper demonstrates both originality and practical significance, with the potential for wide-ranging applications. Minor adjustments to figure annotations, quantitative data presentation, and reference updates will greatly enhance readability and scientific impact.

Reviewer 2 Report
Comments and Suggestions for AuthorsThis paper deals with the active illumination laser gate imaging technology that can improve the shortcomings of backlight imaging technology. Although the effectiveness of the technology was confirmed with the supplementary materials and images, the following content needs to be supplemented in order for the paper to be accepted.
1. The core element of this technology appears to be the method of controlling and synchronizing the timing of the laser pulse and camera gating. However, the current manuscript lacks specific descriptions of this crucial control technology. A more detailed explanation of this process would significantly strengthen the paper.
2. In lines 223-225, you mention that the laser pulse and the camera are synchronized with a nanosecond shutter. However, no specific figures are provided to support this claim. Please include precise timing data to substantiate this statement.
3. The explanation of Figure 1 is insufficient. While the upper figure depicts scattered light and the lower figure shows the reflected signal, the lack of a detailed explanation makes it difficult to discern the significant differences between these two scenarios. Please provide a more comprehensive description of this figure.
4. Figure 3 presents experimental results at 1 second, 5 seconds, and 9 seconds. The significance of these specific time intervals is not clear. Please elaborate on the rationale behind choosing these particular time points and explain their relevance to the study's objectives.
