Laser scanners are efficient, flexible, and reliable measurement devices that combine with localizing technology such as fixed CMMs or articulated arms. This creates interesting options for speed and accuracy, especially for applications involving complex and freeform parts. Laser scanners work by projecting a laser line onto the object under test. The camera sees this image, which is converted into a series of dots based on the pixilation within the camera; the resulting calculation characterizes the measurement.
This paper focuses on the applications of this technology and takes a quick look at the various attributes of state-of-the-art laser scanners.
