LIGHT SCANNING METHOD AND LIGHT SCANNING UNIT |
摘要 |
In a light scanning method of scanning a light beam emitted from a light source on a plane to be scanned, a focal distance of an optical element that converges light emitted from the light source onto the plane to be scanned is sequentially varied to uniform a beam spot diameter at each position on the plane to be scanned where a distance from the light source varies. |

1. A light scanning method of scanning a light beam on a plane to be scanned, comprising the steps of:
light emitting from a light source, varying a focal distance of an optical element sequentially, the optical element converges light emitted from the light source onto the plane to be scanned, to uniform a beam spot diameter at each position on the plane to be scanned where a distance from the light source varies. |
