Abstract
An optoelectronic device detects labels provided with contrasting patterns. A transmitter emits light rays, and a receiver receives the light rays. The receiver includes a receiver output for outputting receiver signals. A reflecting unit periodically guides the light rays within a monitoring range. An evaluation unit for evaluating the receiver signals from the receiver, The transmitter, receiver, and reflecting unit are arranged such that the light rays are guided from said transmitter to said reflecting unit to the label to said reflecting unit to said receiver. The receiver includes at least one light sensitive surface that at least partially encloses the light rays transmitted from said transmitter to said reflecting unit.
Claims22
An optoelectronic device for detecting labels having with contrasting patterns, comprising:
- a transmitter for emitting light rays;
- a receiver for receiving the light rays, said receiver including a receiver output for outputting receiver signals;
- a reflecting unit that periodically guides the light rays within a monitoring range;
- and
- an evaluation unit for evaluating the receiver signals from the receiver,
- wherein said transmitter, said receiver, and said reflecting unit are arranged such that the light rays are guided from said transmitter to said reflecting unit to the label to said reflecting unit and to said receiver, and
- wherein the receiver includes at least one light sensitive surface that at least partially surrounds the light rays emitted from said transmitter.
