In this Letter, we experimentally show that transient phenomenons in self-mixing signals from a moving target contain information about the target reflectivity and distance. These transient phenomenons are well explained with a dynamical model of the laser diode, which is used to trace an abacus giving the target reflectivity and distance from a measured high-bandwidth, self-mixing signal.
