Abstract
A true-color image of a sample is obtained from interference data captured with a color camera. The irradiance of each color on the respective photo-sensor represents the sum of DC components received from the object and the reference surface and a modulated interference component. The color is determined at each pixel by removing the interference component and the reference-surface component from the irradiance data. The color map so derived is then combined with the height map produced with the same data to yield a true-color 3D map of the sample.
