Calibration method for high-accuracy measurement of long focal length with Talbot interferometry: comment

摘要

In a recent paper [Appl. Opt. 51, 2407 (2012)], the authors presented a calibration method for the long focal length Moire fringe measurements to reduce the relative error to less than 0.02%, which was based on two presented results. We tried to reproduce the same results with the information and equations provided but were unsuccessful. (C) 2015 Optical Society of America
