title: Interferometric method for measuring high velocities of diffuse surfaces.
abstract: An interferometric method for measuring the displacement of diffuse surfaces moving with velocities of a few millimeters per microsecond is presented. The method utilizes the interference between two light beams reflected from a constant area of the moving surface at two different angles. It enables the detection of the high-rate velocity variations. A light source with modest temporal coherence and power around 100 mW is needed.
