Abstract
A new signal processing and data acquisition system has been developed that allows a Fourier transform spectrometer to be interfaced to external trans ient digitizers for time-resolved spectroscopy. Time resolution is limited only by the transient digitizer and detection system response time. For the present system it is about 1 ns. The capabilities of this system are demon strated with visible Fourier transform spectra of both scattered laser ligh t and fluorescence from electronically excited NO2 gas.
