Abstract:
1. An apparatus for simultaneously spatially multiplexing IR spectral information for each of a plurality of samples, comprising: at least one IR light source; at least one sample holder which positions the plurality of samples in an optical path; an optically dispersive element in the optical path, wherein an emission from the at least one IR light source interacts with each of the plurality of samples along the optical path to form a corresponding plurality of sample emissions, said plurality of sample emissions interacting with the optically dispersive element to form a corresponding plurality of dispersed sample light beams, each of said plurality of dispersed sample light beams corresponding to a respective one of the plurality of samples; and an IR FPA detector arranged in the optical path, said IR FPA detector having multiple pixels arranged in plural rows and columns, wherein the IR FPA detector detects the corresponding plurality of dispersed sample light beams and provides at least one output which represents the IR spectral information for each of the plurality of samples.
