How does the LK series measure?
The LK series measures using triangulation. A laser diode shines a beam of light to the target. The light will diffuse off the surface and back to the sensor. The light is focused onto a CCD (Charge Coupled Device) detector. As the target moves away from the sensor, the focused spot will move toward one end of the CCD. As the target moves toward the sensor, the focused spot will move toward the other end of the CCD. The position of the laser spot on the CCD is directly proportional to the distance to the target.
