3D scanning and measurement system

13 October 2010 Manufacturing / Production Technology, Hardware & Services

Traqu is a new 3D measurement system from Essemtec, featuring an infrared interferometer. It creates a digital 3D model of an object with an accuracy of a nanometre and allows for any type of measurement to be made subsequently, including volume, height, distance and surface roughness. The measuring principle works with any kind of surface, reflective or matte.

The system scans the surface of an object in 3D. Therefore, all measurements and analysis can be made on the digital model at a later date and even in a different location. Users can freely define any required measurements. The device can also determine layer thickness because an interferometer works similarly to an ultrasound probe. Because of its flexibility and independence, Traqu is suitable for analysis and documentation in the development process, for tasks in quality control or for inspection of incoming goods. The measurement system works at up to a million frames per second.

The 3D scanner is mounted on a precise XY portal and can digitise surfaces up to 400 x 300 mm. Therefore, it can scan a complete PCB at once, even with components on it. There are no shadows, parallax errors or damages because the scanning beam is vertical and low-energy.
