Multi-wavelength Doppler phase shifting interferometry

Abstract

A novel phase-shifting technique, Doppler phase-shifting is introduced to interferometry and holography. Its principle, features and advantages are discussed. The use of multiple wavelengths in this method is also discussed. Their applications such as shape measurement, color holography etc. are presented.
