How the Scanners Work?

Principle of Laser Triangulation

Hermary scanners work on the principle of laser triangulation. A laser beam is projected at a known angle onto a target to be measured; a camera at a known offset from the laser views the projected image.

The angle (θ) at which the camera sees the laser at position A can be calculated from the location of the sensor image at A’. Knowing one side and two angles of the triangle, the distance to position A can be calculated.
