Optical spectroscopy device has spectrally dispersive or diffractive elements influencing wavefronts of interference sub-beam(s) depending on wavelength

摘要

The device has an arrangement for generating an interference pattern and a spatially resolving detector that can acquire the energy of the interference pattern. The wavefronts of at least one of the sub-beams involved in the interference pattern can be influenced depending on the wavelength by spectrally dispersive or diffractive optical elements. Independent claims are also included for the use of a device for optical spectroscopy and for a method for determining the optical spectrum by analysis of a measured interference pattern and for a method of computing an optical spectrum.
