LIFTIRS, the Livermore imaging FTIR spectrometer
- Lawrence Livermore National Laboratory, L-43, Livermore, California 94550 (United States)
The imaging FTIR spectrometer was invented 25 years ago. Only recently, however, with the development of infrared focal plane array technology and high speed microprocessors, has the imaging FTIR spectrometer become a practical instrument. Among the class of imaging spectrometer instruments, the imaging Fourier transform spectrometer enjoys a great advantage in terms of calibratibility, sensitivity, broad band coverage and resolution flexibility. Recent experience with the LIFTIRS instrument is summarized. As a concrete example of the acquisition, calibration, and comprehension of the data from an imaging Fourier transform spectrometer, the case history of a geological sample is discussed in great detail. In particular, the importance of principle component analysis to imaging spectroscopy is especially emphasized. It is shown how the various spatial/spectral constituents within a sample can be detected, located, identified and quantified. {copyright} {ital 1998 American Institute of Physics.}
