Laser optical structure and laser ranging system

The invention provides a laser optical structure and a laser ranging system, and relates to the technical field of laser ranging, the laser optical structure comprises a shell and a laser emitting part, the laser emitting part emits laser towards a first refractor, the first refractor refracts the laser and refracts the laser to a second refractor, and the second refractor is connected with the shell. The second refractor refracts the laser again, the laser is refracted out of the top shell, when the laser makes contact with an obstacle, the laser is reflected, reflected to the second refractor, then reflected to the first refractor and finally reflected to the laser receiver, and the laser receiver receives the laser and carries out distance measurement. The angle of the first refractor is adjusted through the first adjusting part, and the angle of the second refractor is adjusted through the second adjusting part, so that multi-angle detection can be performed, the direction of the top shell is adjusted thr
