摘要： A Fourier spectroscopic analyzer includes: a light receiver that receives a first wavelength component of a first wavelength band and a second wavelength component of a second wavelength band different from the first wavelength band, emits an interferogram to a sample, and outputs a first light reception signal acquired by receiving the first wavelength component and a second light reception signal acquired by receiving the second wavelength component; and a signal processing device that eliminates noise of the first wavelength component and acquires the spectrum by Fourier transform processing using the first light reception signal and the second light reception signal. The first wavelength band is a wavelength band of which a spectrum is acquired among wavelength components included in light that has passed through the sample. The interferogram is interference light and the sample is an analysis target.

摘要： A Fourier spectroscopic analyzer includes: a first light source that emits light including a wavelength component in a first wavelength band which is a wavelength band in which a spectrum of light passing through a sample is acquired and a wavelength component in a second wavelength band different from the first wavelength band; a second light source that emits light including the wavelength component in the second wavelength band; an interferometer that acquires an interferogram which is coherent light from the light emitted from the first light source; a first light coupling optical system that couples light emitted from the second light source to at least one of light emitted from the first light source and the interferogram acquired by the interferometer; a light receiver that outputs a first light-reception signal acquired by receiving light including the wavelength component in the first wavelength band out of the wavelength components included in the light passing through the sample and a second light-reception signal acquired by receiving light including the wavelength component in the second wavelength band; and a signal processor that performs a Fourier transform process on the first light-reception signal and the second light-reception signal to acquire a spectrum of the wavelength component in the first wavelength band with noise removed therefrom.

摘要： A Fourier spectrophotometer includes: a light source; an interferometer configured to obtain first and second interferograms whose intensity distributions are inverted from each other from the light emitted from light source; a multiplexing optical system configured to multiplex the first and second interferograms to irradiate the sample with a resultant interferogram; a demultiplexing optical system configured to demultiplex the first and second interferograms contained in the light passing through the sample; a light receiver configured to output a first light reception signal obtained by receiving the demultiplexed first interferogram and a second light reception signal obtained by receiving the demultiplexed second interferogram; and a signal processing device configured to perform processing for obtaining a noise-removed spectrum of the wavelength component in the analysis wavelength band by using the first and second light reception signals.
