Reviewer 2 Report

In the manuscript entitled “Electro-optic sensor for measuring electrostatic fields in the frequency domain”, Cristiano et al. discuss an approach for electrostatic field measurements using electro-optic (EO) sensor. By arranging two EO sensors in a crossed-polarizers configuration, they demonstrated its capability to measure frequencies below 20 Hz. Theirs measurements are supported by an analytical model and associated simulations. After reading the manuscript, I found it is well-written. Both the experimental data and theoretical simulations seem convincing. Before recommendation, I would like the authors to address the follow points to further improve the quality of the manuscript.

 

1)     I find Fig. 11 and Fig. 13 confusing. What does each color represent? Shouldn't there be a color bar associated with this plot?

2)  More details should be added to the caption of Fig. 16, eg. the red circle, which is only explained in the main text but not in the figure caption.

3)     The dimensions or at least a scale bar should be included in Fig. 17.

4)     It’s a bit draw back that the authors provide no detailed information about the analytical model. As it’s a relatively simple system, some equations would be helpful to better understand/elaborate, eg. the scaling of H1/H2 powers as function of incident electric fields.
