2D Laser Scanners

The laser scanners are intended for non-contact measuring and checking of surface profile, dimensions, sorting and sensing of technological objects, 3D models construction.
The series includes:
    RF627 — universal high-speed scanners;
    RF627Weld — scanners for welding robots;
    RF627Weld-Smart — scanners for welding robots with in-built tracking software (from January 2021);
    RF627AVIKScan —weld seam inspection system;
    RF627Smart — scanners with in-built measurement functions (from February 2021);
    RF629 — ultra-fast scanners, up to 50000 profiles/s (from February 2021).

Operation of the scanners is based on the principle of optical triangulation.

Radiation of a semiconductor laser is formed by a lens in a line and projected to an object. Radiation scattered from the object is collected by the lens and directed to a two-dimensional CMOS image sensor. The image of object outline thus formed is analyzed by a signal processor, which calculates the distance to the object (Z-coordinate) for each point of the set along the laser line on the object (X-coordinate). Scanners are characterized by base distance (beginning of the range), SMR, for Z-coordinate, measuring range (MR) for Z-coordinate, measuring range for X-coordinate at the beginning of Z (Xsmr) and measuring range for X-coordinate at the end of Z (Xemr).
