White Light Scanning

White light scanning is a 3D digitizing technology

that measures the physical characteristics

of an object with an optical measuring

system.

3D white light scanning is the most accurate process for taking the dimensional measurements of an object and then modeling in 3D digitally. It has been improved on with the advances in computing power.

The process of 3D white light digitizing is very complicated. White light scanners use measurements such as fringe contrast, frequency domain analysis, and fourier analysis to create a model. White light scanning uses imaging interferometers to measure optical path difference.

The scanner sends multiple lights towards an object. As multiple scanner lights hit the object, "interference" occurs between the lights. The difference between the lights is measured and the scanner is able to formulate digital coordinates of the object .

The white light scanner compares millions of points on an object, so it is a very precise representation. The data is stored and acts as a 3D model which can be utilized in CAD software.

Benefits

Minimal setup

Non-contact scanning.

Very Fast

High Point Density

Good Point Accuracy

Medium Noise Level

Good for Medium to Large Objects.

White light scanning is useful to many industries. In

production and engineering, white light digitizing is utilized for accuracy in

producing engine blades, part molds, and sheet metal

cuts.

Using fourier analysis, white light scanning can produce detailed topographic and surface maps.

White light scanning is used within the dentistry field. Computer-aided design (CAD) has helped manufacture dental prostheses, provide educational dental training, plan dental surgery, and construct electronic casts instead of stone casts.

The Steinbichler COMET 5 is a white light 3D scanning system. It offers high-speed 3D measurements and the 3D digitizing is completed in a timely manner. It is an ideal solution for demanding industrial manufacturing and product development.
