1. A spectrometer comprising:

  • a lamellar grating interferometer;

    a first optical system adapted to direct radiation from an object onto said interferometer;

    an array of detector elements for detecting said radiation after it has passed through said interferometer and converting said detected radiation into electrical signals, each detector adapted to detect light from a different portion of said object; and

    a processor coupled to receive said electrical signals containing information as to the spectral composition of said radiation from said detector elements, said processor adapted to perform a Fourier transform on said information to obtain a spectral composition of said object.
