The Leica Absolute Tracker AT402 presents the ideal solution for portable probing applications when paired with the established quality of the Leica B-Probe portable probing tool. This single-case portable probing system delivers improvements in measurement process speed and usability as well as customisable hidden-point reach. When added to the already class-leading cableless functionality of the Leica B-Probe, large-volume probing is now simpler and better than ever before.

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.[1] Some examples of laser tracker applications are to align aircraft wings during assembly[2] and to align large machine tools.[3] 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.

A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs,including mechanical,optical, laser,and white light.Depending on the machine, the probe position may be manually controlled by an operator or it may be computer controlled.CMMs typically specify a probes position in terms of its displacement from a reference position in a three-dimensional Cartesian coordinate system

A laser tracker is a measuring device that projects a laser beam onto an optical target that is in contact with an object to be measured, and determines the three-dimensional position of the target. The optical targets known as “retroreflective” because they reflect the laser beam back to its emitted origin point – typically known as a spherically mounted retroreflector (SMR). Dimension values, angles, geometrical tolerances, etc. are determined by software that calculates the 3D coordinates of the retroreflector.

3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models.
A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects. For example, industrial computed tomography scanning, structured-light 3D scanners, LiDAR and Time Of Flight 3D Scanners can be used to construct digital 3D models, without destructive testing.
