Round 1

Reviewer 1 Report

Applied Sciences is a journal with an extremely diversified audience. One of its ambitions is to allow readers from one area to grasp at least some basic ideas of a paper from another area that stimulated their curiosity.

 

In the case of the present paper, a passing reader could wonder why it is so difficult to transmit live holograms. The authors give an answer in the introduction saying that “the required throughput is intolerably high”, but do not explain why in simple terms. It is known that an elementary account of the origin of this can be given by evaluating the number of pixels needed to specify the field distribution at optical wavelengths across even a modest window (say a 10 cm sided square). That would give a clear base to the fact that all the holo transmission methods devised so far are based on the attempt of reducing the information needs by eliminating elements that are redundant for human use, like the suppression of vertical parallax.

 

Apart from this suggestion, I think the paper is a valuable contribution to the research on transmission of live 3D images. Beyond the Benton trick, it makes use of focused image holography, thus reducing image blurring effects. Parallax properties are encoded through multiple image recording.

 

The actual experiment is clearly explained and properly documented.

 

My suggestion is: Accept the paper with optional revision.

Author Response

We would like to thank Reviewers for useful advice and discussions. Actually, after we made amendments according to Reviewer’s comments, the paper has become better structured and vivid.

Reviewer 2 Report

I suggest minor revision and here are my comments:

-Section 2 should be divided in two Sections: Section 2 is experimental setup and its explanations. Section 3 should be the results and discussion. Conclusion would be Section 4.

 

-Please describe in the paper why you have choosen the rainbow hologram?

-One table maybe added before conclusion comparing this work with some of previous ones in the same area.
