Abstract
A display device () for producing images to be viewed by an observer includes an optical system () and a control unit (). The optical system receives input light indicative of an image into a light propagation channel (A) and produces, at an exit pupil (B), output light having a field of view (FOV) corresponding to the image to be presented to the observer (). The light propagation channel has an intensity transfer function map I(x,φ) of the optical system across a lateral dimension x of the exit pupil and an angularspan φ of the FOV. The control unit () modifies the image data which is to be input in the optical system by applying thereto intensity modulation based on a correction intensity map that at least partially compensates intensity non-uniformity in the intensity transfer function map I(x,φ) of the optical system, such that the light output at the exit pupil of the optical system and indicative of the image, has a modulated intensity map which is observed by the viewer with improved intensity uniformity.
