Abstract

A light receiver designed to determine a position or orientation relative to a reference light wherein the light receiver comprises an elongated rod-shaped light receptor with two ends, a light coupler, a light guide, and light detection means at both ends and a signal processor to process the electric signals of the detection means and to determine the relative position and/or orientation by a comparative evaluation of the electric signals. The light guide serves as a light propagation path of defined length for light coupled into the light guide by the light coupler and the signal processor determines the position and/or orientation based on light propagation speed of the reference light propagating in the light guide.
