Abstract
A method and a device for contactless determination of forces and/or moments acting on a hollow cylindrical body (), in which via a light source (), light radiation is produced within the hollow cylindrical body (); measurement signals are recorded by an optoelectronic sensor (); the measurement signals recorded by the optoelectronic sensor () are supplied to the signal processing unit (); the signal processing unit () detects and outputs changes of the measurement signals relative to an initial state determined beforehand by calibration, corresponding to the initial undeformed state of the hollow cylindrical body (); and when a mechanical deformation of the hollow cylindrical body () is present, according to a calibration function or a calculation rule, the signal processing unit () outputs an output signal that describes the forces and/or moments that are causing the mechanical deformation of the hollow cylindrical body ().
