Title:
FOURIER TRANSFORM SPECTROSCOPY METHOD, SPECTROSCOPIC DEVICE, AND SPECTROSCOPIC MEASUREMENT PROGRAM THAT IMPROVE SPECTRAL RESOLUTION AND SPECTRAL ACCURACY
Document Type and Number:
WIPO Patent Application WO/2014/034085
Kind Code:
A1
Abstract:
Provided is a Fourier transform spectroscopy method that removes restrictions on spectral resolution and spectral accuracy in Fourier transform spectroscopy for observing a cyclic repeating phenomenon, that realizes, theoretically, infinitesimal spectral resolution (infinite spectral resolving power), and that can improve spectral accuracy. After accurately and sufficiently stabilizing the repetition cycle of a phenomenon, a temporal waveform is acquired by making a repetition cycle and a time width (observation time window T) for observing the temporal waveform of a phenomenon strictly conform, and by performing a Fourier transform, acquired is a discrete separation spectrum in which the inverse number of the observation time window T is made a frequency data gap. Measurement is repeated while causing the repetition cycle to change, and the gap of the discrete separation spectrum is supplemented. Thereby, in a case of an observation target in which the existence time of a phenomenon is longer than the repetition cycle, the spectral resolution of the obtained discrete separation spectrum becomes infinitesimal (spectral resolving power is infinite) and spectral accuracy is improved.
