Abstract:
An illumination distribution system for distributing high power illumination to a set of projectors. The system includes a display element, such as a spatial light modulator (SLM), receiving light from a laser. The system includes a fiber optic array with connection locations for optical fibers. The system includes projectors that are each coupled to the fiber optic array at one or more of the connection locations with at least one optical fiber. The system includes a controller operating the display element at a first time to display a first hologram and at a second time to display a second hologram differing from the first hologram such that the laser light is split, with equal or unequal splitting ratios, into beams that are selectively directed to the connection locations of the fiber optic array (e.g., based on a 2D routing pattern used to generate the holograms).
