DEVICE FOR DETECTING AN ANGULAR DIRECTION IN WHICH AN OBJECT IS LOCATED

摘要

The invention relates to a device (D) for detecting an angular direction in which an object (2) is located, which is to be used in an optoelectronic system for determining the position of an object (2) on a predefined geometric structure, said device (D) including at least two receivers (R1, R2), each of which have a receiving surface (S1, S2) on which the radiating power received from the object (2), and thus the raw photocurrent generated as output, is dependent on the angle (a,ß) from which the object (2) is viewed along a strictly monotonous dependency curve of the radiating power received with the angle (a,ß) from which the object (2) is viewed. Both receiving surfaces (S1, S2) are placed side-by-side, but each receiving surface lies in a separate plane, wherein the two planes formed therebetween form an angle of less than 150º and thus form a so-called device edge (AD). The device makes it possible to determine the angles (a,ß) from which the object (2) is viewed by each receiver (R1, R2) while taking into consideration that the brightness for each receiver (R1, R2) is identical, but the radiation has different angles (a,ß) of incidence.
