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 one or both ends for detection of guided reference light and a signal processor to process the at least one detection signal of the detection means and to determine the position by an evaluation of the detection signal. The light coupler comprises light absorbing and emitting material like fluorescent or phosphorescent material.
