Abstract: The present invention relates to a laser radar system and a method for obtaining target images. The present invention comprises a light source, a light deflector, and a photo-detector. The light source radiates laser beams. The light deflector is positioned between the light source and a target. The light deflector enables the laser beams to be radiated in other positions of the target as time passes. The photo-detector detects the laser beams reflected from the target according to the radiation of the light deflector. The light deflector comprises a receiving light detection surface having a diameter (D_DA) which satisfies a formula (Sqrt(2) x P_RBS + 2 x D_RBS
