Abstract: In a Fourier-transform spectroscopy apparatus, a scanning mirror is arranged on a light path of scanning light. The scanning mirror delays or advances the scanning light with respect to reference light according to the rotational angle of the scanning mirror from its initial position. A spectroscopic spectrum generating unit generates an interferogram based on the intensity of the detection target light obtained from the detection target, and Fourier transforms the interferogram thus generated. The spectroscopic spectrum generating unit corrects the nonlinearity of the group delay between an envelope of the reference light and an envelope of the scanning light, and corrects the nonlinearity of the phase shift between the respective envelopes.

Abstract: Irradiation light in a visible light region is irradiated to a sample while switching irradiation of infrared light IR having a wavelength that corresponds to the infrared absorption spectrum of an observation target material included in the sample between a first state and a second state. A first image and a second image are generated based on the phase distribution, the intensity distribution, and the polarization direction distribution of the light including the irradiation light that has passed through the sample in synchronization with the switching of the infrared light IR irradiation between the first state and the second state. Subsequently, an output image is generated so as to represent one from among the position, size, and shape based on the difference and/or ratio with respect to the pixel values for each pixel between the first image and the second image.

Abstract: A spatial modulator is provided on a plane conjugate to a sample plane on which a sample is to be placed. The spatial modulator spatially modulates illumination light irradiated to the sample 2 or object light that has passed through or that has been reflected by the sample. A dark-field optical system removes the non-scattered light component of the first object light affected by the spatial light modulator so as to generate second object light. An image sensor records a hologram based on the second object light. A calculation processing apparatus combines complex amplitude information based on the modulation pattern supplied to the spatial light modulator and complex amplitude information based on the hologram with respect to the second object light so as to acquire a phase distribution originating from the sample.

Abstract: Provided is a Fourier transform-type spectroscopic device capable of improving an acquisition speed of a molecular vibration spectrum. The Fourier transform-type spectroscopic device (1) of the present invention rotates a scanning mirror (26b) by rotation of a rotating shaft (26a) to change a light path length of scanning light and delay or advance the scanning light with respect to reference light in accordance with a rotation angle of the scanning mirror (26b) from an initial position, and is thus capable of moving the scanning mirror (26b) at a high speed as compared with a case where a movable mirror is mechanically moved as in a conventional Fourier transform-type spectroscopic device, thereby improving an acquisition speed of a molecular vibration spectrum.
