Abstract
A phase-shifting interferometer with fractional-fringe techniques by a wide-tunable Ti:sapphire laser for three-dimensional range measurement has been constructed. The phase shift in four step by wavelength diversity can be measured with Carre technique that corresponds to the integer and the fractional fringe numbers at a center wavelength.
