Patent ID: 8902421

Claim:
An active-illumination parallel Raman microspectroscopy system for multi-point and full-spectral range Raman imaging, comprising: a laser; a laser line filter configured to purify light from said laser at a desired wavelength; a beam expander configured to expand said purified light from said laser line filter; a spatial light modulator configured to transform said purified light into spot patterns via diffraction; a device comprising at least one objective lens and at least a first tube lens and a second tube lens, said spot patterns passing through said first tube lens and at least one of said objective lens such that said spot patterns excite Raman scattering from said sample producing Raman light, said Raman light passing through at least one of said objective lens and at least said second tube lens; a long-wave pass filter to filter said desired wavelength from said Raman light; and a spectrograph containing a thermal-electrically cooled charged couple device camera configured to receive said Raman light from said long-wave pass filter, wherein said spectrograph contains a diffraction grating to disperse different wavelengths in different directions, wherein said spectrograph is configured to utilize a selected grating dispersion direction, and wherein said spatial light modulator is configured to generate spot patterns in which no two points are allowed to completely overlap along a direction perpendicular to the selected grating dispersion direction.
