title: High signal-to-noise Fourier transform spectroscopy with light emitting diode sources.
abstract: A temperature tuned light emitting diode (LED) has several advantages over conventional sources for Fourier transform spectroscopy. The large radiation density of LEDs, concentrated in a small spectral region, is ideal for high resolution Fourier transform spectroscopy where a high signal-to-noise (S/N) ratio is desired. A simple, inexpensive LED source leads to a superior performance at high resolutions exceeding that of a tungsten halogen lamp, in the visible region of spectrum.
