<p>The spectrophotometer has a photodetector matrix placed in an image plane of the spectrometer, and an interferometer producing interferogram of a light source placed in an input field of the spectrometer. A dispersive device disperses the light parallel to lines of the matrix, and a slit is placed in the plane. The interferometer has spectral resolution lower than a spectral sampling interval of the photodetector along a direction of the lines. The width of the slit is adapted such that the resolution of the system is greater than the interval along a direction of the lines.</p> |
