Description
Die Erfindung geht aus von einer Vorrichtung nach dem Oberbegriff des Anspruchs 1. Es ist schon eine Vorrichtung zur optischen Distanzmessung bekannt (DE-A-43 l6 348), die als Einzelkomponenten eine Sendeeinrichtung zur Aussendung eines gebündelten Messsignals, eine Empfangsoptik zum Einfangen eines an einem entfernten Objekt reflektierten Messsignal-Anteils, einen der Empfangsoptik nach geschalteten opto-elektronischen Wandler und eine Umlenkeinrichtung zur Erzeugung eines Referenzsignals aufweist. Bei der Herstellung des Distanzmessgerätes werden die Einzelbausteine einzeln montiert. Infolge unvermeidbarer Fertigungstoleranzen müssen die Bausteine anschließend im Sinne einer optimalen Funktion der Distanzmessvorrichtung aufeinander abgestimmt und einzeln zueinander ausgerichtet werden.The Invention is based on a device according to the preamble of Claim 1. It is already a device for optical distance measurement known (DE-A-43 l6 348), which as single components a transmitting device to broadcast a bundled Measuring signal, a receiving optics for capturing one at a remote Object reflected measurement signal component, one of the receiving optics switched after opto-electronic converter and a deflection device for generating a reference signal. In the manufacture of the distance measuring device, the individual components individually mounted. Due to unavoidable manufacturing tolerances must Blocks afterwards in the sense of an optimal function of the distance measuring device to each other coordinated and individually aligned with each other.
