title: Laser feedback metrology of optical systems.
abstract: A simple interferometric metrology instrument based on the effect of weak optical feedback on the power output of laser diodes is described. Laboratory demonstrations of the principle applied to the analysis of wavefront aberrations in optical systems is reported.
