A laser radar system capable of active polarization comprises a signal processing unit for sending a control signal; a laser emitting unit for emitting a first laser to a target after receiving the control signal, wherein the laser emitting unit comprises a liquid crystal polarization driver and a liquid crystal polarization component group, and the liquid crystal polarization driver controls a phase delay of the liquid crystal polarization component group to therefore change a polarized state of the first laser; and a laser receiving unit for receiving a second laser reflected off the target and analyzing polarization information of the second laser through the signal processing unit to evaluate surface characteristics of the target.
