LIDAR

LiDAR Principle

  • A Time of Flight (ToF) LiDAR (Light Detection and Ranging) system is used in distance measurement by calculating the flight time between the emission of a light pulse and its return to the sensor.
  • Pulsed semiconductor lasers are used so that their time of flight (ToF) can be measured, these are known as direct-detection laser rangefinders.
  • A low price diode laser or a more powerful pulse semiconductor laser diode at a wavelength of 850~950 nm or 1,550 nm is used in ToF LiDAR.
