Abstract
An optical movement sensor for clearly accurately detecting deformations of a human body. The movement sensor consists of a belt with a buckle made up of two parts which are joined together mechanically by a light-transmitting sensor element. Transmitting and a receiving fibre optic light guides are connected to one part of the buckle in such a way that light emitted by the transmitting light guide passes through the sensor element by way of a polarizer and is coupled to the receiving light guide via an analyzer.
