Abstract
Provided by the present technology is an illumination apparatus including a light source section, a phase modulation section, and a control section. The light source section has a light emitting element. The phase modulation section performs spatial light phase modulation on incident light from the light source section. The control section controls the phase modulation section in such a manner that a plurality of domains formed by dividing a phase modulation plane of the phase modulation section reproduces a light intensity distribution based on a common phase distribution determined on the basis of a Freeform method in a common region on a projection plane.
