Abstract
Multiple-wavelength interferometry is, like classical interferometry, a coherent method, but it offers great flexibility in sensitivity by a n appropriate choice of the different wavelengths and it can be operat ed on rough surfaces. The accuracy of this method depends essentially on the signal processing and on the properties of the source. Practica l considerations for distances in the range of several meters with mic rometer resolution are given.
