Abstract
A self-mixing velocimeter system is demonstrated for the contactless measurements of the tangential speed of a rough surface. This system can be applied to the analysis of the eye movements in a range of angular velocity from 0°/s to 500°/s, also allowing a discrimination of the rotation direction, with a relative maximum error of 10-20%.
