Abstract
Systems and methods for generating 3D representations of shape and color texture of a test surface are described. In one aspect, surface topography interferometers are equipped with a multi-element detector and an illumination system to produce a true-color image of the measured object surface. Color information can be presented as a true-color two-dimensional image or combined with topography information to form a three-dimensional representation of the shape and color texture of the object, effectively creating for a human observer the impression of looking at the actual part.
