Abstract
Opto-electronic measuring arrangement which is largely independent of extraneous light, comprising emitted and compensation light sources, which emit light time-sequentially and in a phased manner, wherein the emitted light is phase-shifted respectively by 180°. An optical receiver receives the light emitted by the emitted light source and reflected by the object being measured together with the light from the compensation light source. The actuation signals for the emitted and compensation light sources are controlled such that the synchronous signal difference occurring in the receiver between the different phases is reduced to zero. The optical coupling between the compensation light source and the receiver diode occurs mainly via an optical system in a printed circuit board on which the compensation light source and the receiver are arranged. The printed circuit board itself, i.e. the FR4 component thereof, may constitute the optical conductor between the compensation light source and receiver diode.
