ABSTRACT:
An angle measuring system for the contactless determination of an angle between a first object and a second object which can be moved with respect to each other, the angle measuring system including a first component having a light source and connected to a first object and a second component having a photodetector and connected to a second object. A grating is connected either to the first component or the second component, the grating having a combined amplitude-phase grating.
