A Photonic Approach for Doppler Frequency Shift Measurement With Dispersion Medium

A Photonic Approach for Doppler Frequency Shift Measurement With Dispersion Medium

We propose and experimentally demonstrate a novel and simple approach to identifying both the direction and value of Doppler frequency shift (DFS) in this paper. A pair of phase modulators, as well as a dispersion medium in between them, are employed in the approach. The different dispersion-induced...
