1. A method for mapping an object, comprising:

  • illuminating the object with at least two beams of radiation having different beam characteristics;

    capturing at least one image of the object under illumination with each of the at least two beams;

    processing the at least one image to detect local differences in an intensity of the illumination cast on the object by the at least two beams; and

    analyzing the local differences in order to generate a three-dimensional (3D) map of the object.
