Thermal Fringe Formation during a Hologram Recording Using a Dry Photopolymer^†

Round 1

Reviewer 1 Report

The authors developed a physical model that predicts quantitatively the fringe formation in large size holographic optical elements, considering the HOE recording geometry, recording conditions and characteristics of the dry photopolymer. Key strategies to avoid thermal fringe formation were studied.

In my opinion, this work has the potential for publication in the Photonics Journal. Only minor corrections need to be addressed:

Please define the acronym HOE in the abstract.

Line 81 - holographic optical elements (HOE) – Please use only the acronym

Fig. 2, 3 - Please define all elements of the figures

Fig 9a, 10a – Please put the legend of each line in these graphs

Fig 19b, 20b, 21b, 22b, 22c – Please insert the caption of the axes.

Reviewer 2 Report

In this paper, the authors present the study about undesired but possible fringe formation during large size HOE recording with a dry photopolymer.  Identify the deformation of the recording element during hologram exposure as the main reason for the fringe formation. This article is clear, concise, and suitable for the scope of the journal. We should accept with only several small suggestions are supplied:
1.  Suggest the authors supply length labels for Fig.4, 5,6,7,19,20.
2. Suggest giving more detail about the complex behavior in Fig.14.

Reviewer 3 Report

1 It is really desirable for us to understand the fringe formation during preparation of HOE. However, there is no any references of this aspect in the manuscript. Please let us know if your work is the first to consider this problem.

 

2 The conclusion is too simple to this long research paper.
