Southlake, Texas-headquartered NVision Inc. has introduced the MAXOS optical scanning system. Compared to a coordinate measuring machine (CMM), MAXOS can reduce the amount of time required to inspect turbine blades, NVision says.
The MAXOS scanner uses a proprietary non-contact probe consisting of a point of white light that allows the collection of individual points at a rate of 70 per second. Like a touch-probe CMM, NVision explains, the unit collects individual points. But unlike a conventional CMM, it continues on its path at high speed and without pausing.
NVision notes that because the MAXOS scanner measures with a single white light point, the cause of inaccuracy and approximation inherent in three-dimensional measurement with a ball probe is eliminated as well.
While originally developed for other turbine uses, this technology could also be used for scanning wind turbine blades, according to an NVision representative.
