Abstract
A sensor () comprising an illuminator (), a receiver () and an analyzer () for detecting and identifying an analyte having a characteristic absorption band that is present in a sample region (). The illuminator includes an illumination source () for illuminating the sample region with spectral energy across at least a portion of the characteristic absorption band. The receiver includes a detector () for sensing predetermined portions of the spectral energy band and for creating a sample spectral data vector (). The analyzer uses the spectral data vector and known characteristic data to detect and identify the analyte.
