These devices are a hybrid of a coordinate measuring machine (CMM) arm or articulated arm and a noncontact laser scanner head. One of the advantages of this type of device is that the arm probe orients the data capture scanning head in space and helps to organize the point cloud data, especially when in comes to knitting together captured surface patches. Scanners mounted on an articulating arm allow the user to "paint" the surface with the scanner and watch the surface develop on a computer screen. These devices are made by companies such as Metris, Perceptron, Laser Design, and Kreon.
