Abstract
A system comprising a light source configured to illuminate a sample under measurement. The system includes a detector configured to receive reflected light from the sample, and the detector generates a signal representing the reflected light. A spatially variable filter (SVF) is positioned in the optical path. The SVF is configured to have spectral properties that vary as a function of illuminated position on the SVF.
