Abstract
A diffractive structure arranged to spatially modulate light transformable by a viewing system into a target image. The diffractive structure is configured to generate a plurality of discrete light patterns. Each light pattern corresponds to a different part of the target image. The shape of each discrete light pattern substantially corresponds to the shape of an entrance aperture of the viewing system.
Claims18
A diffractive structure arranged to spatially modulate light transformable by a viewing system into an image, wherein the diffractive structure is configured to route light into a plurality of hologram channels, each hologram channel corresponding to a different part of the image.
A method of calculating a hologram of an image, the method comprising at least one step including cropping (light paths during calculation) in accordance with the entrance pupil of the viewing system to form a hologram that, when illuminated, forms spatially modulated light, wherein continuous light channels of the spatially modulated light correspond with continuous regions of the image.
