    Industrial automation engineering firms that plan, design, and construct factories have benefited greatly from technological developments in terms of both quality and cost. How does 3D Laser Scanner work?

    A 3D scanner, like a Total Station, works by projecting a laser into a surface and collecting its reflection. The scanner will compare the phase shift of the reflected wavelength and the frequency differences in order to calculate the object’s location in space. The internal mirror of the 3D scanner may be turned through a complete circle of vertical motion. Furthermore, the scanner will horizontally spin in a complete circle. This setup, which consists of a vertically-rotating mirror and a horizontally-rotating scanner, generates a spherical 3D point cloud.
