Abstract: A method and system for inspecting an object is provided. The system includes a measurement device that measures 3D coordinates of points on a surface of the object. A display is coupled to the device and is sized to be carried by an operator. One or more processors cooperate with the measurement device, to perform a method comprising: determining 3D coordinates of the points while the object is being measured; aligning an electronic model of the object to the points while the object is being measured; determining a variance between the electronic model and the points while the object is being measured; and displaying on the display an indicator when the variance exceeds a threshold while the object is being measured.

Abstract: A system and method of determining 3D coordinates of an object is provided. The method includes determining a first set of 3D coordinates for a plurality of points on the object with a structured light scanner. An inspection plan is determined for the object, which includes features to be inspected with a remote probe. The points are mapped onto a CAD model. The features are identified on the plurality of points mapped onto a CAD model. A visible light is projected with the scanner proximate a first feature of the features. A sensor is contacted on the remote probe to at least one first point on the first feature on the object. A first position and orientation of the remote probe are determined with the scanner. A second set of 3D coordinates of the at least one first point are determined on the first feature on the object.

Abstract: A method for measuring a distance includes modulating the light beam at a first frequency, receiving a second beam by the optical detector to produce a first electrical signal having the first frequency and a first phase; modulating the light beam at a second frequency different than the first frequency; receiving the second beam by the optical detector to produce a second electrical signal having the second frequency and a second. After these steps, the retroreflector is moved while modulating the light beam continuously at the second frequency; and a first distance to the retroreflector is determined based at least in part on a the first and second frequencies and phases.
