Verfahren und Vorrichtung zur elektrooptischen Entfernungsmessung

摘要

A process and device are proposed for the electro-optical measurement of distance based on the pulse delay method. A number of individual light signal pulses are emitted at predetermined and differing intervals, so that after a number of measurement intervals which determine the measurement zone have elapsed, a pulse sequence is detected. Using mathematical estimation methods, the temporal position of the detected pulse sequence in relation to a reference pulse sequence can be determined and used to determine the delay time. By emitting individual pulses at long intervals and high peak power and subsequently combining them to form a pulse sequence, the accuracy of the distance measurement process is significantly improved.
