Beschreibung
Zusammenfassung:	An optical radar includes an optical signal receiving unit and an optical signal pickup unit. The optical signal receiving unit is configured for receiving a reflected light. The optical signal pickup unit is coupled to the optical signal receiving unit and includes a first optical signal filtering unit and a second optical signal filtering unit. The first optical signal filtering unit is configured for filtering out a first interference pulse of the reflected light, wherein the first interference voltage value of the first interference pulse is higher than a reference voltage. The second optical signal filtering unit is coupled to the first optical signal filtering unit and is configured for generating a clock signal. The clock signal has a clock pulse and filters out a second interference pulse of the reflected light that does not correspond to the clock pulse in time point.
