Abstract: Provided is an image laser radar optical system with inscribed light transceiving modules. The image laser radar optical system includes a zoom lens type light transmitting module (10) which receives an emitted laser beam (A) having an inherent numerical aperture of a light source, and converts the emitted laser beam (A) into a transmitting laser beam (a) having a constant light divergence angle to emit the transmitting laser beam to an object (T) at a given distance, wherein the constant light divergent angle of the transmitting laser beam (a) varies depending upon the numerical aperture. Therefore, the size of the laser beam can be obtained corresponding to the intention of a user even though various kinds of laser beams having different numerical apertures are used. In particular, since an optical axis of the laser beam emitted from an object lens (15) of the zoom lens type light transmitting module (10) coincides with an optical axis of the laser beam received by a receiving object lens (31) of a light receiving module (20), an area overlapped by each other is minimized, and the size of a scanner (200), which is additionally equipped in the module, is also minimized.
