| 摘要 |
A laser illuminator comprising at least one optical diffusion means capable of modifying an optical diffusion condition ( 3 ) and at least one optical suppression means for suppressing divergence of light ( 100 ), wherein the optical diffusion means and the optical suppression means are disposed along an optical path of a laser beam ( 6 ) radiating from a laser source and the laser beam is converted into a diffused and non-divergent light beam ( 6 - 2 ) for illuminating or exciting an object by passing through the optical diffusion means and the optical suppression means.
