Amplification synchronization module and device based on MEMS laser radar

The utility model provides an amplification synchronization module based on an MEMS laser radar. The amplification synchronization module comprises M first amplification chips and a second amplification chip. Each first amplification chip comprises K paths of input ends and an output end, outputs of K paths are switched through 1-3 control pins, and M output ends of the M first amplification chips are connected and connected to an input of the second amplification chip. The circuit form not only can avoid optical interference and electrical interference between array APDs and realize accurate distance measurement, but also can save an amplification chip and a post-stage time identification module and a timing module, and can easily realize miniaturized and low-cost three-dimensional laser radar scanning distance measurement. The utility model also provides a synchronization device based on the mems laser radar, which adopts the amplification synchronization module to realize synchronization among mems, laser,
