Laser Scanners, White Light Scanning Systems and Analog Scanning Devices. Each one has its own advantages and disadvantages based on the job specifics.
Laser scanners have the most flexibility of any non-contact scanning method. They can be mounted on a coordinate measuring machine, attached to portable measuring arms as well used with the Leica Tracker. Laser scanners regardless of where they are mounted have the ability to measure all sides of the component being inspected.
White light scanning systems, or blue light as in some cases, are by far the fastest method of data accumulation. They are ideal for smaller components or large batch inspection of the same component. Once programmed, they operate automatically, even in conjunction with a rotary table or a loading robot.
Analog scanning devices maintain constant contact with the component. They are generally mounted on a direct computer-controlled coordinate measuring machine – their advantage is precision. Analog scanning devices can also function as a tactile measuring system and blend tactile measurements with scanning measurements.
