Title: Two-wavelength double heterodyne interferometry using a matched grating technique
Issue Date: 1991 Zeitschriftenartikel Applied optics 30 (1991), S. 3139-3144. URL
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.
