Abstract
A 3D object generating apparatus includes an optical-transparent, a laser light generating module, and a controller. The laser light generating module includes a light emitter for outputting a spot beam, a polygon mirror, a flat-field convergent lens, and a flat-field optical sensor. The polygon mirror directs the spot beam into a linear beam. The flat-field convergent lens is positioned between the laser light generating module and the optical-transparent component, and a flat-field scanning route is formed after the linear beam passed through the flat-field convergence lens. The flat-field optical sensor is positioned on the flat-field scanning route senses an optical power of the linear beam and generates a sensed signal. The controller is electrically connected to the laser light generating module and the flat-field optical sensor, and receives the sensed signal and calibrates the optical power of the spot beam based on the sensed signal.
