Micro-columnar lens array-based laser plane generation device

The invention discloses a micro-columnar lens array-based laser plane generation device. The device comprises a laser light source module, a rotation prism module, a micro-columnar lens array module and an adjustment mechanism, wherein the micro-columnar lens array module comprises a plurality of miniature columnar lens which are closely arranged on a slab waveguide substrate of a polymethyl methacrylate material, the laser light source module emits a beam of collimating laser, the rotation prism module is used for deflecting a transmission direction of the laser by 90 degrees, a laser ray after transmitting can be broaden along a radial direction of the columnar lens after the laser irradiates the micro-columnar lens array module, a laser sector is formed in a space, and the slope and theheight position of the laser sector can be flexibly changed by controlling a stepping motor or the rotation prism module. The generation of the laser plane can be achieved only by a simple device, and moreover, the slope and
