Abstract
A beam-steering projection system includes a light source configured to emit a light in response to image signal, a phase light modulator, and a spatial light modulator. The phase light modulator is configured to receive the light from the light source and to apply a spatially-varying phase modulation on the light, thereby to steer the light at an illumination angle and generate a first steered light. The spatial light modulator is configured to receive the first steered light, to apply a spatially-varying amplitude modulation on the light, to steer the light towards a projection optics system and to generate a second steered light. A plane of a secondary image constructed after the phase light modulator and before the spatial light modulator is parallel with the phase light modulator.
