  • Spectrum measurement method using fourier transform type spectroscopic device
    Patent number: 10317283
    Abstract: A method for measuring spectrum by Fourier-transforming an interferogram of an infrared interference wave acquired with an interferometer, including a step of over-sampling intensity signals of the interference wave at positions (D1, D2, . . . ) of a movable mirror set on the basis of a wavelength ?1 of a semi-conductor laser, and a step of interpolating intensity signals (I1?, I2?, . . . ) that would be obtained when the interference wave is sampled at positions (D1?, D2?, . . . ) of the movable mirror set on the basis of a wavelength ?0 of a He—Ne laser, by using the over-sampled intensity signals (I1, I2, . . . ), for calculating the spectrum with the interferogram based on the interpolated intensity signals (I1?, I2?, . . . ) and for an efficient use of conventional stored spectrum data which are measured based on the wavelength ?0.
