Laser rotation imaging equipment and laser imaging method

The embodiment of the invention provides laser rotation imaging equipment and a laser imaging method, which are used for improving the precision and efficiency of laser imaging. The laser rotation imaging device comprises a processing platform, a laser rotation platform and a controller. The machining platform comprises a cylindrical shell with the hollow interior, and a fixing assembly used for fixing a workpiece to be machined is arranged on the inner side wall of the cylindrical shell. The laser rotating platform is arranged on the inner side of the cylindrical shell, and a laser array composed of a plurality of lasers distributed in the central axis direction of the cylindrical shell is arranged on the laser rotating platform. The laser array can rotate along a preset direction relative to the inner side surface of the cylindrical shell and can move along the central axis of the cylindrical shell; a laser emergent surface of the laser array is opposite to an exposure surface on the to-be-processed workpie
