Paper Abstract

A Fourier transform spectrometer with heterodyne modulation using a moving diffraction grating has been developed for the NIR region. The grating simultaneously acts as a beam splitter and a modulator, which realizes optical frequency shift of incident light for increasing the sensitivity of measurement by heterodyne modulation technique. The difference of diffraction angle is compensated by a collimating lens or a mirror and plane mirrors.
