Abstract
A rainbow artifact mitigation system includes an angular dependent filter configured to receive light and to transmit light according to one or more angular transmission functions. The one or more angular transmission functions define light transmission as a function of incident angle for the angular dependent filter, The angular dependent filter is configured to at least partially mitigate transmission of light for at least some incident angles above 40°. The angular dependent filter comprises a plurality of nanostructures, and the nanostructures of the plurality of nanostructures are arranged in an array with one or more sub-wavelength periods. The one or more angular transmission functions comprise at least two different angular transmission functions for different regions of the angular dependent filter.
