500 -=== 2.8.1 Principle of Distance Measurement ===
501 -
502 -
503 -The LiDAR probe is based on TOF, namely, Time of Flight principle. To be specific, the product emits modulation wave of near infrared ray on a periodic basis, which will be reflected after contacting object. The product obtains the time of flight by measuring round-trip phase difference and then calculates relative range between the product and the detection object, as shown below.

511 -With optimization of light path and algorithm, The LiDAR probe has minimized influence from external environment on distance measurement performance. Despite that, the range of distance measurement may still be affected by the environment illumination intensity and the reflectivity of detection object. As shown in below:

553 -* Measure high reflectivity object such as: Mirror, Smooth ceramic tile, static milk surface, will have possible wrong readings.
554 -* While there is transparent object such as glass, water drop between the measured object and the LiDAR sensor, the reading might be wrong.
555 -* The LiDAR probe is cover by dirty things; the reading might be wrong. In this case, need to clean the probe.
556 -* The sensor window is made by Acrylic. Don't touch it with alcohol material. This will destroy the sensor window.
