We report the development of a data acquisition system which can be used with any commercial Michelson interferometer to carry out time‐resolved Fourier transform spectroscopy with a time resolution of one microsecond. The sensitivity and spectral resolution of the experiment are limited only by the interferometer. The instrument occupies one slot on a conventional VME enclosure (6U height). It includes all hardware and firmware to control the experiment which generates the spectral transients and to collect the time‐resolved interferograms. We are presently transferring this design to a single 6U height printed circuit board (with a mezzanine), in order to make it available as a standalone system for use with any VME platform.
