Abstract
A device for optoelectronic distance measurement includes an emitter having a first end for emitting a measuring beam to an object to be measured and a second end, a receiver for receiving the measuring beam reflected or dispersed back from the object to be measured and for converting it to a measurement signal, a signal processing device for filtering the measurement signal and a reference signal, and a control and analysis device for analyzing the information of the measurement signal and the reference signal so as to determine the distance from the object to be measured. The second end of the emitter is used to emit a reference beam which is received by the receiver and converted to form the reference signal.
