The goal is to solve two fundamental problems in Fourier optics: the presence of unwanted orders of diffraction in holographically reconstructed images and insufficient angles of light deflection in the first diffractive order. Those problems limit the applicability of holography in wearable near-eye displays, highly demanded due to the recent re-birth of virtual/augmented reality. Novel aspheric diffractive combiners will be designed to increase the field of view of a spatial light modulator with ultra dense pixels. The synchronized gating of illumination will be used to minimize the stray zero order light, manifesting as light reflex. Pixel micro-apodization will be attempted, which shall hide the higher diffractive orders manifesting as ghost images. The latest algorithms of noiseless computer holography will be used for the first time. A working demonstrator of a wearable holographic near-eye display will be constructed to prove the solution of the mentioned scientific problems. (Polish)

L’objectif est de résoudre deux problèmes fondamentaux en optique de Fourier: la présence d’ordres non désirés de diffraction dans les images holographiquement reconstruites et l’insuffisance des angles de déflexion de la lumière dans le premier ordre diffractive. Ces problèmes limitent l’applicabilité de l’holographie dans les écrans près des yeux portables, très demandés en raison de la récente renaissance de la réalité virtuelle/augmentée. De nouveaux combinés diffractifs asphériques seront conçus pour augmenter le champ de vision d’un modulateur de lumière spatiale avec des pixels ultra denses. Le calibrage synchronisé de l’éclairage sera utilisé pour minimiser la lumière d’ordre zéro errant, se manifestant comme réflexe de lumière. La micro-apodisation des pixels sera tentée, ce qui masquera les ordres diffractifs plus élevés se manifestant sous forme d’images fantômes. Les derniers algorithmes d’holographie informatique sans bruit seront utilisés pour la première fois. Un démonstrateur fonctionnel d’un écran holographique olographe portable sera construit pour prouver la solution des problèmes scientifiques mentionnés. (French)
