LiDAR is the abbreviation for “Light Detection and Ranging” or “Laser Imaging Detection and Ranging”. It is the method to measure the distance against an object, or analyze the behavior of an object, by sending pulsed laser irradiations.

The vertical motion of laser irradiation is scanned by galvanometer scanner which drives in high speed, and the horizontal motion is scanned by 360-degree rotating stage. LiDAR makes 3-D representations by capturing the reflected laser irradiation by detector.
