Crosstalk-Free Multiplane Full-Color Holography Based on the Space Division Method
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors have introduced a full-color holography based on space division method to develop a new solution for three-dimensional color holographic display. This work is intriguing and shows promise. However, I believe the manuscript requires further investigation and modifications to enhance its overall quality. Here are some specific points for improvement:
1. There is a typo in Line 96. The third part pertains to the design method rather than the principle of color image reproduction.
2. The authors should explain why the centers of the signal domains are designed to deviate from the geometric centers of the projected areas.
3. The authors should provide an explanation of how to design the patterns of the DOE and include more detailed descriptions of the fabrication results of the DOE.
4. The discrepancy in SSIM and PSNR between the experimental results and simulation results, as shown in Figure 6, appears to be much larger than that of Figure 7. Could the authors explain this phenomenon when comparing Figure 6 and Figure 7?
Given the points raised, it is advisable to conduct a thorough revision of the manuscript before considering it for publication in Photonics.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe main question addressed by the research is how to achieve crosstalk-free multiplane full-color holography using a space division method. The research focuses on proposing a solution for three-dimensional color holographic display by dividing the hologram into three regions for the R, G, and B trichromatic hologram components. The goal is to reconstruct different color images on single and multiple planes, addressing the challenges of crosstalk and providing a method for full-color display.
In terms of the topic's originality and relevance, it is a novel approach to address the challenges in achieving full-color holography. The use of a space division method to separate trichromatic components and reconstruct images at different projection depths suggests an innovative approach. The relevance is evident in the context of advancing holographic display technology.
In essence, the research introduces an innovative approach to overcome challenges in full-color holography, particularly in achieving crosstalk-free multiplane displays. The proposed method is supported by simulations and experiments, and the compact experimental setup suggests potential practical applications in the field of holographic displays.
Some technical comments:
The figures are reasonably good quality, the tables are perfectly arranged. The equations are professionally edited.
The "Conclusions" section of the manuscript provides a concise summary of the findings. However, to enhance the completeness of the research, it is advisable for the authors to provide a more detailed discussion on the implications of their results. This may include insights into the practical applications of the proposed method, potential limitations, and avenues for future research. Expanding this section would offer readers a deeper understanding of the significance and broader context of the study. The Abstract could also be a bit longer, more informative.
While the references are relevant, it is suggested that the authors consider expanding the list to include a more comprehensive review of existing literature. This can strengthen the theoretical foundation of the research and demonstrate a thorough understanding of the field. Incorporating additional references from related studies, advancements, or alternative methodologies would contribute to the robustness of the paper. It is essential to acknowledge and build upon the existing body of knowledge in the holography field to situate the current research within the broader scientific context.
Overall, I recommend a minor revision mainly due to the Conclusion section.
