DISPLAYING SPECTROMETER (VERSIONS) Russian patent published in 2008 - IPC G01J3/45 

FIELD: physics; optics.

SUBSTANCE: invention pertains to optical instrument making. In the spectrometer, interferometers, the mirrors of which do not have reflecting surfaces, are arranged relative the axis of the optical system, along which filtered radiation propagates at an angle φ, equal to Brewster angle. The spectrometer is fitted with an extra polaroid. The focal distance of the objective, located in front of the matrix receiver, and the distance between the mirrors of the interferometer are such that, on the outermost rows of the matrix, falls radiation with wavelength, linked to the upper and lower edges of the working spectral range respectively.

EFFECT: provision for instant registration of space and spectral information and the possibility of fast switching of operation modes.
