Abstract
This application discloses distance detection apparatuses. The distance detection apparatus includes a light source, a transmitting and receiving lens, a detector, and an optical path change element. The light source is to emit a beam. The transmitting and receiving lens is to collimate the beam emitted by the light source, and converge at least a part of return light of the beam reflected by a to-be-detected object. The detector is placed with the light source on a same side of the transmitting and receiving lens, to convert at least a part of return light that passes through the transmitting and receiving lens into an electrical signal. The optical path change element is to change an optical path of the beam emitted by the light source or the return light that passes through the transmitting and receiving lens.
