1. A method for laser distance measurement, comprising:
obtaining, from a control circuit, a synchronization signal;
generating, by at least one signal generator, a first periodic signal, a second periodic signal, and a third periodic signal based on the synchronization signal;
emitting, by a laser emitting device, a laser beam toward a target, the laser beam being generated under a modulation of the first periodic signal;
generating, by an optical detector, a measurement signal in response to a signal mixing of the second periodic signal and a reflected laser beam from the target; and
determining a distance to the target based on the measurement signal and the phase of third periodic signal.
