|Applicants:||TWO TREES PHOTONICS LIMITED
|Title:||LIGHTING DEVICE FOR HEADLIGHTS WITH A PHASE MODULATOR|
There is provided a lighting device arranged to produce a controllable light beam for illuminating a scene. The device comprises an addressable spatial light modulator arranged to provide a selectable phase delay distribution to a beam of incident light. The device further comprises Fourier optics arranged to receive phase-modulated light from the spatial light modulator and form a light distribution. The device further comprises projection optics arranged to project the light distribution to form a pattern of illumination as said controllable light beam.
