摘要： A light scanning device for reading or writing information by irradiating laser light onto a scanning plane. The light scanning device comprising a light source for irradiating the scanning plane with laser light along an optical path, and a rotating disc with at least one lens having at least one aspheric surface disposed in the optical path of the laser light irradiated from the light source for providing a microlight spot forming a light scanning line on the scanning plane.
