The distance detection device for an unmanned aerial vehicle is a kind of distance detection device for an unmanned aerial vehicle.

[0003] The prior art patent document with the publication number CN210015229U discloses a distance detection device. Both the first region and the second region include a light-transmitting substrate coated with a polarizing film. The polarization direction of the polarizing film is the same as the polarization direction of the emitted light pulse. And a non-reciprocal polarization rotation device is arranged on one side of the transceiver element, so that the polarization direction of the light pulse is perpendicular to the polarization direction of the return light passing through the non-reciprocal polarization rotation device. The optical path changing element is placed on the same side as the transceiver element and the light source, and the effective aperture of the transceiver element is larger than the effective aperture of the optical path changing element. The distance detection device includes a plurality of the light sources, a plurality of the detectors corresponding to the plurality of the light sources, and a plurality of optical path changing elements corresponding to the plurality of the light sources and the detectors. The light source includes at least one edge-emitting laser. The detector includes at least one avalanche diode, which is used to receive at least part of the return light converged by the transceiver element and convert the received return light into an electrical signal. The size of the photosensitive surface of the avalanche diode is larger than the size of the spot of the return light, and the difference between the two sizes is equal to or greater than the assembly error. The light source includes an edge-emitting laser line array formed by regularly arranging a plurality of edge-emitting lasers.
