Two-wavelength double heterodyne interferometry using a matched grating technique

Not Accessible

Your library or personal account may give you access

Abstract

Two-wavelength double heterodyne interferometry is applied for topographic measurements on optically rough target surfaces. A two-wavelength He–Ne laser and a matched grating technique are used to improve system stability and to simplify heterodyne frequency generation.
