Abstract

The set-up consists of a double-grating system which realises 2 successive auto-correlations of a grille, that is to say a two-dimensional repartition of opaque and transparent zones. The flux transmission of this set-up is identical to the classical slit spectrometer but the equivalent slit height can be up to one meter for a 1 meter focal length objective. Contrarily to a one-grating grille spectrometer previously proposed, no important background substraction by demodulation is needed. This system is then usable in spectral ranges where gratings are usually used.
