Multiple-laser light source

A light source to supply light for a light projector, comprising:

• a plurality of individual lasers spaced in an array, each of the lasers operable to emit a corresponding beam of light;
• a plurality of lenses, each associated with one of the individual lasers and positioned to collimate light from the corresponding lasers;
• one or more mirrors associated with each individual laser positioned to redirect the beams of collimated light to provide an aligned and non-overlapping array of patches of parallel light beams that are spaced more closely than the spacing between the individual lasers;
• and
• a dynamically addressable phase modulating device having an active area divided into a number of elements that are each positioned to receive a substantially non-overlapping patch of collimated parallel light beams from one of the individual lasers, wherein the elements of the phase modulating device are individually controllable to adjust the phase of the patch of collimated parallel light beams received by the element.
