| 英文摘要 | A projector is provided, having a light source emitting a laser beam; an optical element, which the laser beam emitted by the light source passes through; a projection component, projecting an image onto a projection surface by irradiating the laser beam emitted from the optical element onto the projection surface while scanning. The optical element has an incident surface, where the laser beam emitted by the light source is incident; and an emitting surface, where the laser beam incident to the incidence surface is emitted. A first lens surface, shaping a beam shape of the laser beam from elliptic into circular by astigmatism generated in the laser beam, is formed on one of the incident and the emitting surfaces, and a second lens surface, converting the laser beam from a divergent beam into a parallel beam, is formed on the other one of the incident the emitting surfaces. |
