Abstract:
A scanner system, comprising:a sample illumination source, wherein said illumination source is comprised of a laser, wherein said laser simultaneously emits radiation of a first wavelength and a second wavelength;a scan head for scanning an area of a sample held within a sample support, wherein said scanning is along a first direction and a second direction, wherein said scan head directs said radiation from said source to a portion of said sample;a detection system for monitoring radiation emitted by said sample, wherein said detection system comprises a first detector monitoring radiation of a third wavelength and a second detector monitoring radiation of a fourth wavelength, wherein said first and second detectors simultaneously monitor radiation emitted by said sample, and wherein each detector outputs a signal corresponding to the intensity of said radiation; anda wavelength selection system coupled to said detection system, wherein said wavelength selection system determines said third and fourth wavelengths of radiation monitored by said first and second detectors.
