A white light scanner -LRB- WLS -RRB- is a device for performing surface height measurements of an object using coherence scanning interferometry -LRB- CSI -RRB- with spectrally-broadband , `` white light '' illumination .. coherence scanning interferometry. coherence scanning interferometry. CSI. Coherence scanning interferometry. Different configurations of scanning interferometer may be used to measure macroscopic objects with surface profiles measuring in the centimeter range , to microscopic objects with surface profiles measuring in the micrometer range .. micrometer. micrometre.
