3D laser scanning uses a line of laser light to capture the shape of physical objects.  This technology is a non-contact and non-destructive way to capture the object’s exact size and shape and creates a 3D digital copy of the object on a computer.   The process is very fast, gathering up to 750,000 points per second, and equally as precise, measuring to ±.0005″.  Once the 3D digital copy is made the object can be reverse-engineered and modified in CAD.
