Scanner software supports 3D laser triangulation for metal surfaces
EyeVision software by EVT now also supports a 3D laser triangulation sensor with blue laser. The EyeScan AT 3D scanner is better suited to scanning metal or metallic surfaces, says the company.
Most 3D scanners use red laser technology, but the EyeScan AT 3D Blue uses optically superior blue laser technology. The blue-violet laser is claimed to have better scan results.
The blue laser has a shorter wavelength than a red one, which allows it to deliver scanning results with higher resolution and up to a 50% reduction in data noise.
The shorter wavelength means that the laser speckle pattern is smaller, so that a sharper depth image is generated. The blue laser has more effects when scanning metal, because a blue laser is narrower and finer than a red laser line, says the company.
The blue laser, combined with 20,000 profile/s allow complex component parts and surfaces to be captured with high accuracy, it is claimed. The fast scans are possible due to the short exposure time.
A Schleimpflug optic ensures that a sharp image is possible, even with a big lens and short exposure time, says the company, adding that the lens quality means no lens correction necessary.
The high dynamic range with 3time exposure makes it possible to inspect dark and bright objects in one scan, without a decrease in speed.
