Patent number: 7471386Abstract: The disclosure relates generally to methods and apparatus for using a fiber array spectral translator-based (“FAST”) spectroscopic system for performing spectral unmixing of a mixture containing multiple polymorphs. In an embodiment, a first spectrum of a mixture containing polymorphs of a compound is obtained using a photon detector and a fiber array spectral translator having plural fibers. A set of second spectra is provided where each spectrum of the set of second spectra may be representative of a different polymorph of the compound.

Patent number: 7337066Abstract: A system and method for automated baseline correction for Raman spectra is disclosed which may operate as a piecewise-linear baseline correction function. In an embodiment, a first set of data points from a Raman spectrum are determined to be baseline data points, a second set of data points from the Raman spectrum are determined to be baseline data points where the second set of data points are not contiguous with the first set of data points. The gap between the first and second set of data points is bridged by a straight line thereby forming an estimated baseline. The estimated baseline is smoothed and then subtracted from the Raman spectrum resulting in an adjusted-baseline Raman spectrum.Type: GrantFiled: December 8, 2006Date of Patent: February 26, 2008Assignee: ChemImage, CorporationInventor: Jason H.
