The FARO Laser Scanner Photon works by sending an infrared laser beam
into the center of a rotating mirror. This deflects the laser on a vertical
rotation around the environment being scanned; scattered light from
surrounding objects is then reflected back into the scanner. To measure the
distance FARO's Laser Scanner uses the phase shift technology. This means
that the laser beam is modulated with constant waves of different lengths.
The distance from the scanner to the object is accurately determined by
measuring the phase shifts in the waves of the infrared light.
HYPERMODULATION

greatly enhances the signal-to-noise ratio of the
modulated signal with the help of a special modulation technique. The X, Y,
Z coordinates of each point are then calculated by using angle encoders to
measure the mirror rotation and the horizontal rotation of the Laser
