Abstract
An optical detecting assembly includes: a photosensitive element configured to receive an optical signal and convert it into an electrical signal; and a light guide member comprising a first portion for receiving a first light beam from a rotating light source at a first time point and guiding the first light beam to the photosensitive element and a second portion for receiving a second light beam from the rotating light source at a second time point and guiding the second light beam to the photosensitive element. A distance between the optical detecting assembly and the rotating light source is calculated based on a distance between the first portion and the second portion, a time difference between the first time point and the second time point, and a rotating speed of the rotating light source.
