In this paper we demonstrate a novel method of direct, frequency domain, spectrum analysis relying on the manipulation of microwave-modulated optical pulses using chromatic dispersion. In our approach the utility of dispersion for signal processing is extended when fiber of opposite dispersion sign and appropriate length is added to a preceding link to perform an inverse Fourier transform (IFT).
