Polarization phase-shifting Newton interferometer for plane optical surface measurements

Opt Lett. 2012 Feb 15;37(4):467-9. doi: 10.1364/OL.37.000467.

Abstract

This Letter introduces a polarization phase-shifting Newton interferometer that can be utilized for plane optical surface measurements, a setup constructed to realize the interferometer, and the experimental results from the use of the setup. The results confirm not only the validity but also the feasibility of the interferometer.
