Handheld amplitude-modulated continuous wave laser ranging device

The utility model discloses a handheld amplitude-modulated continuous wave laser distance measuring device, which comprises a frequency signal generating module, a laser modulation transmitting module, a first signal receiving module, a second signal receiving module, a difference frequency phase measuring module and a data display module, the frequency signal generation module is electrically connected with the difference frequency phase measurement module and the laser modulation emission module. The difference frequency phase measurement module is electrically connected with the first signal receiving module, the second signal receiving module and the data display module. The laser modulation transmitting module excites a first optical signal to the first signal receiving module and excites a second optical signal to a target object; the first signal receiving module sends a first target signal to the difference frequency phase measurement module; the second signal receiving module sends a second target si
