The utility model discloses a four beam laser three -dimensional imaging system based on three coaxial opposite afocal telescopes. Its characterized in that: four ways laser gets into one new face coaxial three anti - afocal telescope receiving system respectively via four off -axis visual fields behind target surface scattering, after the mirror reflection is turned back to the visual field, adopt the color separation film to carry out the wave band separation, and the signal acquisition to laser echo both can have been realized to the laser receiving passageway, and area array imaging channel can realize taking a picture to laser footmark two -dimensional space target again to realize the formation of image of multi -beam laser three -dimensional. A receiving telescope's of multiple laser beam reflex circuit sharing in the current laser active detection technique a difficult problem has been solved to this patent, adopts this patent the coaxial three anti - afocal telescopes in big visual field, utilize the off -axis visual field to combine laser receiving passageway and area array imaging channel, can measure at least four bundles laser beam echoes in the overall arrangement.
