Methods and systems for extracting the optical signal parameters necessary to display constellation diagram of a digitally encoded optical signal are provided. The digitally encoded optical signal is separated into two signal components. Through a coherent detection scheme, information from one signal component is compared with information from the other signal component to which a delay is imposed. Differential phase information can therefore be obtained for two consecutive data pulses without requiring receiving and processing speeds matching the data bit rate.
