title: Laser velocimeters: lower limits to uncertainty.
abstract: Laser velocimeters based on many-particle scattering or rough surface scattering are considered. It is shown that the established lower limits to the accuracy are not fundamental limits. Both linear and nonlinear signal processing may enhance the performance. Generic schemes for the processing are presented, and limitations are discussed.
