We present a Fourier Transform spectrometer where as an interferogram, fringes of equal thickness (Fizeau fringes) are recorded instead of the usual fringes of equal inclination (Haidinger rings). An image of the Fizeau fringes being formed on the diode array of a CCD camera allows us to scan the interferogram without moving a mirror or any other element. As the entire interferogram is registered at the same time, AC and even pulsed light sources can be analyzed. The disadvantage is low spectral resolution because the maximum path difference is limited by the size of the diode array.
