Absolute distance interferometry with two-wavelength fringe visibility measurement
Abstract
A new version of interferometer construction for absolute distance measurement is presented. It is based on measuring the contrast of a two-wavelength interference pattern with using a CO2 laser generating a pair of optical wavelengths simultaneously.
