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. 920 - 921 -[[image:1654831757579-263.png]] 922 - 923 - 924 - 925 -== 3.2 Distance Measurement Characteristics == 926 - 927 -With optimization of light path and algorithm, The LiDAR probe has minimized influence from external environment on distance measurement performance.
