| Abstract | In this paper, we report a Doppler lidar in which the laser frequency is stabilized and the backscattered light frequency is discriminated by a multi-peak and a less-peak atomic Faraday anomalous dispersion optical filter (FADOF), respectively. The transmission spectrum of the FADOF is stable as it is based on an atomic transition, and slightly tunable with a magnet due to Zeeman effect. The high frequency stability of the FADOF provides a high velocity accuracy; and the tunability of the FADOF transmission spectrum makes the measurement range flexible. We describe an experimental lidar system based on cesium FADOFs, and the experimental error is of +/- 0.74 m/s over velocities ranging from -40 to +40 m/s. (C) 2012 Elsevier Ltd.
