3D Scanner Types

Short Range 3D Scanners

Short Range 3D scanners typically utilize a Laser triangulation or Structured Light technology.

Laser based 3D Scanners

Laser based 3D scanners use a process called trigonometric triangulation to accurately capture a 3D shape as millions of points. Laser scanners work by projecting a laser line or multiple lines onto an object and then capturing its reflection with a single sensor or multiple sensors.

Projected or Structured Light 3D Scanners

Historically known as “white light” 3D scanners, most structured light 3D scanners today use a blue or white LED projected light. These 3D scanners project a light pattern consisting of bars, blocks or other shapes onto an object.

Medium and Long Range 3D Scanners

Long range 3D scanners come in two major formats - Pulse based and phase shift – both of which are well suited for large objects such as buildings, structures, aircraft, and military vehicles.

Coordinate Measuring Machine (CMM)

A coordinate measuring machine (CMM) is used primarily to inspect parts. The machine can be controlled manually or through controlled offline through software and computers. Measurements are defined by attaching a probe to the machine.

Arm based 3D Scanners and Probe systems

An armed based 3D scanning or probing system is similar to a coordinate measuring machine (CMM) in the fact it can use a touch probe to measure a part.

Optically tracked 3D Scanners and Probe Systems

Optically tracked 3D scanning and probing systems use a set of cameras to track the location of the 3D scan head or probe in 3D space.
