Abstract
The present disclosure relates to an optical ranging device. The optical ranging device comprises a housing, a bottom cover, an emitting lens, a receiving lens and a circuit board. The emitting lens and the receiving lens are fixed on the circuit board. The circuit board comprises a light emitting module, receiving module and data processing and controlling module. An infrared light emitted by a light source of the light emitting module passes through the emitting lens and the housing successively and enters the external environment. The infrared light reflected by the object passes through the housing and the receiving lens successively and is received by the receiving module which is connected to a signal processing and controlling module. The distance between the optical ranging device and the object is calculated based on the Time of Flight principle.
