Abstract:
1. A Fourier transform spectrometer (FTS) data acquisition system comprising: a FTS spectrometer comprising a drive controller, the FTS spectrometer configured to receive a spectral signal and a laser signal; a wideband detector in communication with the FTS spectrometer and configured to receive the spectral signal and laser signal from the FTS spectrometer, and to produce a composite signal from the laser signal and the spectral signal; an analog to digital (A/D) converter in communication with the wideband detector and configured to receive the composite signal and to digitize the composite signal; and a signal processing unit configured to receive the composite signal from the converter and to perform filtering of the laser signal and the spectral signal and demodulate the laser signal, to produce velocity corrected spectral data.
