A range-resolving continuous wave Doppler Lidar is presented based on principles of optical low-coherence reflectometry (OLCR) and using a source with a bandwidth in the MHz range. As opposed to OLCR the range scanning is not done by changing the length of the reference path in the interferometric setup. Rather, a CW source with synthetic phase noise is used enabling numerical range scanning after each single measurement. The latter feature also is in sharp contrast to conventional CW Lidar. Our concept can be applied to wind sensing as well as to remote vibrometry and differential absorption Lidar. © 2013 SPIE.
