METHOD AND SYSTEM FOR RECONSTITUTING COLOUR INFORMATION OF A SAMPLE MEASURED BY WHITE LIGHT OPTICAL PROFILOMETRY, AND APPLICATIONS OF SAID METHOD

摘要

The invention relates to a method for reconstituting colour information of a sample measured by white light optical profilometry, comprising an acquisition (21) of interferograms at a plurality of points or pixels of said sample, said method also comprising, for at least one measurement point: - calculating (22) the optical spectral density of the interferogram, - determining a spectral reflectance from said optical spectral density, and - processing (24) said spectral reflectance to generate colour information of said sample (17).
