Abstract
A lighting device according to the present technology includes: a light source unit that has a light emitting element; a spatial light phase modulator that generates a plurality of reproduced images at intervals on an image surface by performing spatial light phase modulation on incident light from the light source unit; and a projection unit that superimposes and projects the plurality of reproduced images on a projection surface via different projection lenses.
Claims18
A lighting device, comprising:
- a light source unit that has a light emitting element;
- a spatial light phase modulator that generates a plurality of reproduced images at intervals on an image surface by performing spatial light phase modulation on incident light from the light source unit;
- a projection unit that superimposes and projects the plurality of reproduced images on a projection surface via different projection lenses;
- and
- a control unit that changes a position or a shape of the reproduced image by controlling a phase modulation pattern in the spatial light phase modulator.
