    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)

    Ziel ist es, zwei grundlegende Probleme in der Fourier-Optik zu lösen: das Vorhandensein unerwünschter Beugungsordnungen in holographisch rekonstruierten Bildern und unzureichenden Winkeln der Lichtumlenkung in der ersten diffraktiven Reihenfolge. Diese Probleme beschränken die Anwendbarkeit von Holographie in tragbaren Nah-Augen-Displays, die aufgrund der jüngsten Wiedergeburt der virtuellen/augmentierten Realität stark gefordert werden. Neuartige asphärische diffraktive Mähdrescher werden entwickelt, um das Sichtfeld eines Raumlichtmodulators mit ultradichten Pixeln zu erhöhen. Die synchronisierte Beleuchtung wird verwendet, um das streunende Null-Bestelllicht zu minimieren, Manifestieren als Lichtreflex. Pixel-Mikroapodisierung wird versucht, die höheren diffraktiven Ordnungen zu verbergen, die sich als Geisterbilder manifestieren. Die neuesten Algorithmen von Noiseless Computer Holography werden zum ersten Mal verwendet. Ein Arbeitsdemonstrator eines tragbaren holographischen Nahaugendisplays wird gebaut, um die Lösung der genannten wissenschaftlichen Probleme zu beweisen. (German)

    Het doel is om twee fundamentele problemen op te lossen in Fourier optica: de aanwezigheid van ongewenste orden van diffractie in holografisch gereconstrueerde beelden en onvoldoende hoeken van lichtdoorbuiging in de eerste diffractieve orde. Deze problemen beperken de toepasbaarheid van Holografie in draagbare near-eye displays, die sterk gevraagd wordt door de recente wedergeboorte van de virtuele/augmented reality. Nieuwe asferische diffractive combiners zullen worden ontworpen om het gezichtsveld van een ruimtelijke lichtmodulator met ultra dichte pixels te vergroten. De gesynchroniseerde gating van verlichting zal worden gebruikt om het verdwaale nulordelicht te minimaliseren, dat als lichtreflex aanwijst. Pixel micro-apodisatie zal worden geprobeerd, die de hogere diffractieve orden Manifesting als spookbeelden zal verbergen. De nieuwste algoritmen van Noiseless computer Holography zullen voor het eerst worden gebruikt. Een werkende demonstrator van een draagbare holografische near-eye display zal worden gebouwd om de oplossing van de genoemde wetenschappelijke problemen te bewijzen. (Dutch)

    L'obiettivo è quello di risolvere due problemi fondamentali nell'ottica di Fourier: la presenza di ordini indesiderati di diffrazione in immagini ricostruite olograficamente e angoli insufficienti di deformazione della luce nel primo ordine diffrattivo. Questi problemi limitano l'applicabilità dell'olografia nei display a occhi quasi indossabili, molto richiesti a causa della recente rinascita della realtà virtuale/aumentata. I nuovi combinatori diffrattivi asferici saranno progettati per aumentare il campo visivo di un modulatore di luce spaziale con pixel ultra densi. Il gating sincronizzato dell'illuminazione sarà utilizzato per ridurre al minimo la luce randagia di ordine zero, manifestando come riflesso della luce. Verrà tentata la micro-apodizzazione dei pixel, che nasconderà gli ordini diffrattivi superiori che si manifestano come immagini fantasma. Gli ultimi algoritmi del computer Noiseless Holography saranno utilizzati per la prima volta. Un dimostratore funzionante di un display olografico olografico indossabile sarà costruito per dimostrare la soluzione dei suddetti problemi scientifici. (Italian)
