Abstract:
In accordance with the principles of the invention, a lamellar grating interferometer breaks the radiation down into its wavelength components. The two sets of teeth of the grating are moved relative to each other. The spectral output of the interferometer is focused on an array of detectors and data is stored for a large number of positions of the grating teeth. The collected data is then Fourier transformed to recover the spectrum of the radiation.
