Laser trackers are instruments that accurately measure large objects by determining the positions of optical targets held against those objects. The accuracy of laser trackers is of the order of 0.025 mm over a distance of several metres. Some examples of laser tracker applications are to align aircraft wings during assembly and to align large machine tools. To take measurements the technician first sets up a laser tracker on a tripod with an unobstructed view of the object to be measured. The technician removes a target from the base of the laser tracker and carries it to the object to be measured, moving smoothly to allow the laser tracker to follow the movement of the target. The technician places the target against the object and triggers measurements to be taken at selected points, so

  • Ein Tracking-Interferometer ist ein Messgerät, das 3D-Koordinaten von Objektpunkten erfassen kann. Sie bestehen aus einem Interferometer, dessen Laserstrahl automatisch einem Reflektor folgen kann. Lasertracker werden zur Digitalisierung von Objekten, zur Messung großer Bauteile in der Qualitätssicherung, zur Kalibrierung von Werkzeugmaschinen und in der Geodäsie verwendet.
  • Лазерный трекер (to track (англ.) — следить) — измерительный прибор, в основе которого лежит принцип слежения за отражателем с помощью луча лазера.
  • Le laser tracker est un instrument de mesure de longueurs permettant de réaliser des mesures rapides et précises dans les trois dimensions, en aéronautique, automobile, robotique, industrie mécanique des grandes pièces, etc. Il est aussi appelé "laser de poursuite" par erreur de traduction transmise et empruntée par certaines sociétés françaises car il ne "poursuit" pas mais "repère" des objets et "relève" leurs coordonnées, et devrait donc être appelé Laser de repérage ou de relevé. C'est un instrument de repérage et de relevé. Il ne court après rien, il ne poursuit rien, il repère l'emplacement et le positionnement d'objets visés, afin de relever leurs coordonnées tridimensionnelles.

  • Le laser tracker est un instrument de mesure de longueurs permettant de réaliser des mesures rapides et précises dans les trois dimensions, en aéronautique, automobile, robotique, industrie mécanique des grandes pièces, etc. Il est aussi appelé "laser de poursuite" par erreur de traduction transmise et empruntée par certaines sociétés françaises car il ne "poursuit" pas mais "repère" des objets et "relève" leurs coordonnées, et devrait donc être appelé Laser de repérage ou de relevé. C'est un instrument de repérage et de relevé. Il ne court après rien, il ne poursuit rien, il repère l'emplacement et le positionnement d'objets visés, afin de relever leurs coordonnées tridimensionnelles. Il est utilisable presque partout. Selon le modèle et la marque, il peut être transporté en bagage à main. La précision est de l’ordre de 5 µm/m et ceci jusqu’à 160 mètres. Aujourd’hui, trois principaux fabricants de ce type d’instrument existent et se partagent le marché des prises de mesures via des systèmes portables : Automated Precision Inc. est l’inventeur de l'appareil, alors qu'Hexagon et FARO Technologies fournissent également ce système.

The technician removes a target from the base of the laser tracker and carries it to the object to be measured, moving smoothly to allow the laser tracker to follow the movement of the target. The technician places the target against the object and triggers measurements to be taken at selected points, sometimes by a remote control device. Measurements can be imported into different types of software to plot the points or to calculate deviation from the correct position. The targets are known as "retroreflective" because they reflect the laser beam back in the same direction it came from (in this case, back to the laser tracker). One type of target in common use is called a spherically mounted retroreflector (SMR), which resembles a ball bearing with mirrored surfaces cut into it.
