Operating Principle
Distance Measurement: Time of Flight (ToF)
1) A laser diode emits a beam of ultrashort laser pulses onto the target object.
2) The laser pulses are diffusely reflected after hitting the target object. The returning beam is detected by an optical sensor.
3) Distance to the object can be accurately measured by calculating the time between laser emission and receipt.
𝑑 =
𝑐𝑡
2
d: distance
c: speed of light
t: travel time of the laser beam
