Abstract (en)
[origin: EP0989477A2] The operating device comprises a positioning element (1) with at least two degrees of freedom, and a device (3, 5, 6, 9, 11) for an optical evaluation of the position of the positioning element. There is a unit (3, 11) for an optical variation of a ray of light (LS, LR) with respect to its intensity or spectral characteristics. This is activated with the positioning element, and the change is detected with an optical sensor (6, 9).
