3D Laser Scanning
3D laser scanning
• There are two primary types of 3D Laser Scanning: time-of-flight scanners and phase-shift scanners.
• Time-of-flight laser scanners emit a pulse of laser light that is reflected off the scanned object. A sensor measures the time of flight for the optical pulse to travel to and from the reflected surface. The distance the pulse traveled is then calculated using the following equation:
Distance = (Speed of Light * Time of Flight)/2

3D laser scanning
• In phase-shift scanners, a laser beam with sinusoid ally
modulated optical power is emitted and reflected off an
object. The reflected light is then detected and compared
with the emitted light to determine the phase shift. The
time of flight can then be determined from the following
equation:
Time of Flight = Phase Shift / (2* Modulation
Frequency).
• The values calculated are then substituted in to the first
equation to find the distance.
