Your library or personal account may give you access

Abstract

With the application of multiwavelength digital holography in rough environments such as machine tools, we cannot rely on the complete absence of vibrations. The evaluation of temporal phase-shifting in sections allows to determine and take into account random sub-wavelength tilt of the sensor with respect to a work piece. In this regard, measurements inside a machine tool are evaluated and discussed.
