Summary: | The invention discloses a laser radar, a flight time acquisition method thereof, a distance measurement method and a storage medium, the laser radar comprises a control unit, a laser and a photoelectric detector, the control unit is used for generating an optical pulse trigger signal; the laser is connected with the control unit and is used for being triggered by the light pulse trigger signal to emit a first distance measurement light pulse signal and a second distance measurement light pulse signal, and the second distance measurement light pulse signal is amplified by an amplification light path in the laser and has internal time delay; the photoelectric detector is used for being connected with the control unit and used for receiving the first ranging light pulse signal and conducting photoelectric conversion on the first ranging light pulse signal so that the control unit can obtain the emission moment of the first ranging light pulse signal; the photoelectric conversion unit is used for receiving an ech |
