We demonstrate a coherent lidar that uses a broadband femtosecond fiber laser as a source and resolves the returning heterodyne signal into N spectral channels by using an arrayed-waveguide grating. The data are processed incoherently to yield an N-times improvement in the Doppler measurement of a surface vibration. For N = 6 , we achieve a sensitivity of 153 Hz, corresponding to a 0.12 mm s motion, in 10 ms despite a signal that is speckle broadened to 14 kHz. Alternatively, the data are processed coherently to form a range image. For a flat target, we achieve a 60 μ m range resolution, limited mainly by the source bandwidth, despite the dispersion of 1 km of optical fiber in the signal path.
