New type interference selective modulation spectroscopy.
A new method of interference spectroscopy is described. The spectral element is detected photoelectrically by taking the interference between the reflected and the diffracted beams by a modified Michelson interferometer without any computation. The spectrum is scanned by the rotation of the diffraction grating of the interferometer. Modulation of the spectral signal is carried out by the vibration of the reflecting mirror. The principle of the method and the first results are described. Source effects are also discussed.
