Optical distance measuring device has measuring uncertainty adjusted in dependence on measuring range of target object and/or measuring time for distance measurement

摘要

The measuring device has at least one transmitter (22,24) providing a modulated measuring beam (16,26,36) directed towards a target object (20), with reception of the reflected measuring beam (17,44), used for determination of the distance of the target object by a control and evaluation device (28,58). The measuring uncertainty of the measuring device is adjusted in dependence on the measuring range of the target object and/or the measuring time for the distance measurement. An Independent claim for an optical distance measuring method is also included.
