Abstract

This application provides a laser ranging apparatus, a rangefinder and a ranging method. The apparatus includes a processor, a first pulse generator, a second pulse generator, a mixer, and a laser transceiver module; the processor controls the first pulse generator to output a first pulse signal and controls the second pulse generator to output a second pulse signal; the mixer is configured to combine the first and second pulse signals to generate a reference intermediate frequency signal; the laser transceiver module is configured to emit a laser pulse toward a measured object based on the first pulse signal and obtain a target intermediate frequency signal for distance calculation based on the first and second pulse signals and a measurement pulse signal; the processor verifies the target intermediate frequency signal according to the reference intermediate frequency signal and calculates a distance to the measured object using verified target intermediate frequency signal.
