Position measuring system

Abstract

A position measuring system for determining spatial position information includes at least one light source and at least one optical receiving unit. The receiving unit has a scanning grating and an optoelectronic detector arrangement whose light-sensitive surfaces are oriented in the direction of the scanning grating. The detector arrangement has two detector regions arranged in a detection plane mirror-symmetrically to a first axis of symmetry that extends through the center of the detector arrangement in the detection plane, in which the first axis of symmetry is oriented orthogonally to the longitudinal extension direction of the detector regions. The two detector regions have the shape of an isosceles, acute-angled triangle whose triangle tips are oriented with the tip angle in the direction of the center of the detector arrangement.
