Abstract
An illumination apparatus comprising, a light source that emits a laser beam, a lens array on which the laser beam is illuminated, a plurality of element lenses having a diameter greater than or equal to the laser beam are arranged in the lens array, the lens array being rotatable around an optical axis of the laser beam, wherein the two lens arrays are arrayed in an optical axis direction of the laser beam, and the element lenses in each lens array are arranged such that a boundary between the element lenses adjacent to each other radiates from a rotation center of the lens array and a direction in which the element lens of one of the lens arrays traverses the optical axis of the laser beam is orthogonal to a direction in which the element lens of the other lens array traverses the optical axis of the laser beam.
