  • Patent number: 11585757
    Abstract: A device includes a plurality of imaging pixels in a spatial pattern with a formation of features disposed over the pixels. A first and a second feature of the formation of features are disposed over a first pixel. A first luminophore is disposed within or over the first feature. A second luminophore is disposed within or over the second feature. A structured illumination source is to direct at least a portion of first photons in an illumination pattern to the first feature at a first time, and to direct at least a portion of second photons in the illumination pattern to the second feature at a second time. The structured illumination source includes an illumination pattern generator having an illumination pattern generator actuator connected to the illumination pattern generator to cause the illumination pattern to translate or rotate relative to the formation of features.
