3D laser sensor handles reflective and diffuse surfaces

01 April, 2019

The Canadian 3D scanning specialist LMI Technologies has developed a laser line profile sensor which, it claims, is unique in its ability to scan both reflective (specular) and diffuse surfaces simultaneously. For example, the Gocator 2512 sensor can generate a precise 3D scan of a mobile phone’s cover glass in a surrounding metal or plastic frame, inspecting critical parameters such as flushness, gap and offset.

The sensor uses a special laser projection technology that can handle a wide range of surface angles, material types and surface colours. It copes with challenging surfaces including transparent, anti-glare, coated, low/high contrast, UV and glossy finishes. LMI says that rival laser profilers use a collimated laser beam that cannot deliver the same performance.

“The sensor’s unique optical design delivers exceptional performance in challenging specular scanning applications, in a more cost-effective package than competing technologies such as confocal scanners,” says LMI’s senior director of applications, Chi Ho Ng.

The sensor has onboard data processing and built-in measurement tools.
