<p>An illumination apparatus and an image production apparatus including a plurality of laser beams are disclosed wherein a variation of the intensity distribution caused by a secular change or the like can be compensated to obtain illumination light having a high degree of uniformity even if some laser beam exhibits a drop in intensity or misses. The illumination apparatus includes a light source section including a laser light source, an optical system into which a plurality of laser beams are introduced, and a detection section for directly or indirectly detecting a light intensity distribution on a focal plane of the optical system. The illumination apparatus further includes an adjustment section for varying the light intensity distribution on the focal plane based on the detection information of the detection section.</p> |
