Abstract: The spectral information acquisition system includes an illumination optical system configured to illuminate an object being moved and a spectral optical system configured to disperse light from the object illuminated by the illumination optical system. The illumination optical system includes a separation element configured to separate a light flux emitted from a light source into a first polarized light flux having a first polarization state and a second polarized light flux having a second polarization state, and a phase plate configured to change the polarization state of at least one of the first polarized light flux and the second polarized light flux. The first polarized light flux illuminates the object from a first direction, and the second polarized light flux illuminates the object from a second direction that is different from the first direction.

Abstract: An optical filter includes a filter array including filters two-dimensionally arrayed and a band-pass filter. The filters includes first and second filters. A transmission spectrum of each of the first and second filters has local maximum values of transmittance at three or more wavelengths included in a first wavelength region. The band-pass filter passes light in a second wavelength region including two or more wavelengths of the three or more wavelengths and not including one or more wavelengths of the three or more wavelengths. The filter array and the band-pass filter are disposed so that (a) the band-pass filter is located on an optical path of light that passes through the first and second filters or (b) the first and second filters are located on an optical path of light that passes through the band-pass filter.

Abstract: In a spectrometry setup where a first spectral component dominates a second spectral component having a different wavelength, diffraction of the first spectral component as it passes through the optical train of the spectrometer can produce spectral noise that obscures detection of the second spectral component. To reduce the spectral noise, the light from the spectrometer is subject to spatial filtering or interference such that effects of the first spectral component are removed, or at least reduced. The second spectral component can then be more readily detected by a detector after the spatial filtering or interference. In embodiments, the spatial filtering or interference may be provided by a filtering module, which may be installed in existing spectrometry setups or form part of a unitary spectrometry system.
