KNOWLEDGE BASED SPECTROMETER |
摘要 |
<p>A sensor and method for remotely determining a presence of a particular substance based on spectral data of the particular substance is disclosed. The sensor includes a sampling module configured to detect radiation from a particular substance using an interferometer, wherein the sampling module includes a control module that is configured to guide and measure spacing of samples taken by the sampling module; a focal plane module configured to detect and convert an interference pattern produced by the interferometer into a series of digital samples; a reference spectra modification module configured to modify reference spectra by modifying according to the measured spacing of samples and an instrument line shape of the sampling module; an estimation module configured to receive the converted series of digital samples and transform the non-uniformly spaced digital samples into frequency space using band centers determined from reference spectra as modified by the instrument line shape of the sampling module; a comparison module configured to compare the transformed digital samples against a database of known chemical signatures; and a determination module configured to determine the presence of the particular substance based on the results of the comparison.</p> |
