Light output system with reflector and lens for highly spatially uniform light output

A display system comprising:

• an array of light emitters;
• an array of reflectors, each reflector comprising:
• a light input opening for receiving light from a respective light emitter;
• a light output opening;
• and
• reflective interior sidewalls extending between the light input opening and the light output opening, the reflective interior sidewalls configured to provide angularly uniform light output;
• and
• an array of Fourier transform lenses, each of the Fourier transform lenses being arranged proximate the light output opening of a respective reflector of the reflectors, each of the Fourier transform lenses being configured to receive light from the respective reflector and to transform the light from the respective reflector into lens output light having increased spatial uniformity relative to the light received from the respective reflector, each of the reflectors having an associated Fourier transform lens forward of the light output opening of the respective reflector;
• a light modulating device configured to receive light outputted by the array of reflectors through the Fourier transform lenses;
• and
• at least one waveguide including at least a first waveguide comprising at least one light incoupling optical element configured to receive light from the light modulating device and at least one light outcoupling optical element configured to output light,
• wherein a spatial layout of the light emitters matches a spatial layout of the reflectors, and
• wherein the spatial layout of the reflectors, in planar view, overlaps with the spatial layout of the light incoupling elements such that the reflectors correspond one-to-one with a spatial layout of the light incoupling optical elements.
