LED lighting enhances 3D scanners performance

Monday, 19 September 2011 08:29

In the seek of new technologies to improve 3D cloud of points acquisition, AQSENSE, one of the 3D machine vision leading companies, has started exploring LED lighting. Hand in hand with Effilux, the French innovative company dedicated to led systems for the machine vision industry, a cool white-light, 50μm line C-mount LED (EFFI-Lase_CM_1_000 model) has been applied to highly demanding scans where resolution was the key point.

The performance of laser systems, offering a great field of view, is good enough for average requirements where resolutions of hundreds of microns are enough. However, when better resolutions are required, a laser limitation appears: the speckle. This phenomenon, consisting of a random granular pattern caused by the laser reflection on rough surfaces, can blind some points acquisition, limiting the minimum resolution achievable.

LED lighting, on the other hand, does not provides the same visual field as lasers but avoids this speckle limitations allowing greater resolutions and thus being the perfect option for small surfaces scanning.

With this new technology AQSENSE opens a new door to its costumers, allowing very high resolution acquisition while keeping the speed and robustness of SAL3D library for alignment, measurement and manipulation of the acquired clouds of points.
