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.

An illumination apparatus, comprising:
- a light source section that has a light emitting element;
- a phase modulation section that performs spatial light phase modulation on incident light from the light source section;
- and
- a control section that 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 a basis of a Freeform method in a common region on a projection plane, wherein the control section uses, as the common phase distribution, a phase distribution that is obtained by performing a scaling process according to sizes of the domains on a phase distribution calculated by the Freeform method.
