This application discloses an obstacle detection apparatus and method, and an unmanned aerial vehicle (UAV). The obstacle detection apparatus includes a distance measurement and calculation unit, a receiving tube connected to the distance measurement and calculation unit, at least two emitting tubes connected to the distance measurement and calculation unit, and a measurement controller connected to the at least two emitting tubes. The measurement controller is configured to control the at least two emitting tubes, and the receiving tube is configured to receive an optical signal, the optical signal received by the receiving tube being formed after an optical signal emitted by the emitting tube is reflected by an obstacle. The distance measurement and calculation unit is configured to: obtain a phase of the emitted optical signal and a phase of the received optical signal, and calculate a distance between the obstacle and the obstacle detection apparatus based on a phase difference between the phase of the emitted optical signal and the phase of the received optical signal. In this way, a range of obstacle measurement can be effectively expanded.
