The interferometer and method in order to revise vis-a-vis dispersion and/or method null in order to increase the spectrum resolution of the interferometer of this type

摘要

In order to compensate for dispersion, and a method for increasing the spectral resolution of the interferometer of this type (57) [Abstract] The present invention, and relates to an interferometer (1) of the two-beam to electromagnetic radiation. Generates a _½⁰ polarization state P that is defined in part electromagnetic wave polarizer disposed in the optical path (8) comes into the arms of the interferometer, the polarization state is independent of wavelength , can be made different for the beam two components. Sign in (λ ₁₎ deflecting P _1/2 each spectral component λ _i changing the polarization state ⁰_½ P of the partial wave as a function of the wavelength λ using the (11, 12) optical elements and can It may be of. Analyzer placed at the output of the interferometer (9) transmits an adjustable polarization state P _det, the phase difference of the wavelength dependency of the additional portions waves of the spectral components to generate a γ (λ) thereby. It is possible to set a (λ) γ to increase the spectral resolution of the interferometer, or for correcting the dispersion.
