Power Testing of Aspheric Lenses Based on Transmission Phase Deflectometric Method
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors present a technique for measuring lens power using a transmission phase deflection method and propose a system calibration method that combines Direct Linear Transformation (DLT) with the pinhole model. This detection technique offers advantages such as full aperture, high curvature, high precision, and rapid detection. I believe this method is significant practical value for real-time, fast lens testing. However, the following problems still need to be addressed:
1. How do environmental factors such as lighting affect the test results? How is the influence of lighting controlled in the experiment?
2. In this paper the five-step phase shift method was used to extract the phase, please elaborate on the advantages of this method.
3. Are there constraints on the distance between the screen and the lens during the experiment, and how does changing the distance affect the experimental results?
4. Does the period of the fringe map have an effect on the results of the lens refractive power test, and if so, please elaborate on the effect in detail?
5. What are the advantages of the calibration method proposed in this paper that combines direct linear transformation (DLT) and pinhole modeling compared to existing calibration methods?
6. Describe the main sources of error in the experiment and how they can be minimized?
7. Based on this research, what new areas or technological improvements might future research explore? For example, how can testing speed be further improved or more complex optical surfaces be handled?

Reviewer 3 Report
Comments and Suggestions for AuthorsBrief Review of manuscript entitled “Power Testing of Aspheric Lenses Based on Transmission Phase Deflectometric Method” by Q. Wu et al.
The Transmission Phase Deflectometric Method is suggested as substitute of Hartmann, Ronchi, Moire and other methods to tests aspheric lenses. Theory and some experimental results are shown.
In page 6, line 181, it is mentioned that a “Sine” image is shown in the monitors. Instead of that word use the word “Sinusoidal”, Explain in the text why you use sinusoidal fringes.
When this sinusoidal fringes are shown. Does the monitor has the resolution to show a “real sinusoidal pattern”. Is it importan that the fringes are sinusoidal?.
In line 187 it is mentioned a distance of 6.444 mm. Does this means that a precision of 4 microns is needed?.
In line 208 it is mentioned that the lens was placed in the
set up. What was the distance between the lens and the screen?.
It is better to give results when several lenses are tested. Not just one.
