ABSTRACT:
A method and apparatus for determining a phase relation of a signal in which a spectrum thereof includes a spectral component at a central optical frequency f.sub.0 and frequency spikes f.sub.n =f.sub.0 .+-.nF, where n is an integer. The apparatus includes device (29, 26, 28, 30 and 32) for producing signals representative of phase differences between two frequency spikes for each pair of adjacent frequency spikes of the frequency spikes f.sub.n.
