Abstract

The comparison between two-wavelength and two-spacing projection phase-stepping interferometry for real object contouring is presented. Single exposure reflection hologram with two-frequency generating temperature stabilized diode laser is realized. Theoretical approach, experimental results as well as the assessment of sensitivity and uncertainty of the measurements are discussed.
