Abstract [en]

In a method for touch-free determination of the translatory or angular position of a body, a defined measuring path (M) on the body (K) in the direction of said translatory or angular motion of the body (1) is detected spot-wise by means of an optical sensor head (1), which emits laser light towards the measuring path and provides an output signal responsive to light reflected from said path (M), the sensor head (1) and the body (K) with the measuring path (M) being movable relative to each other. In order to provide for an exact position determination with high resolution in an inexpensive way the invention suggests that the surface profile or characteristics of the body (K) along the measuring path (M) is scanned by illumination from the sensor head (1), which consists of an optical pick-up for compact discs.
