Abstract
A method for calibrating light is adapted to a 3D object generating apparatus including a housing, an optical-transparent component, and a laser light generator. The housing has an accommodating space and an opening communicating with the accommodating space. The optical transparent component is arranged on the opening, and the laser light generator is arranged within the accommodating space. The method includes the following steps: providing a first photodetector and a controller, the controller is electrically connected to the first photodetector and the laser light generator; using the controller to drive the laser light generator to generate the light and perform a scanning procedure; and stopping the scanning procedure when the first photodetector detects the light generated by the laser light generator, and then performing a 3D object generating procedure in the working region by moving the laser light generator with a preset distance.
