Résumé
We explore the implementation of dynamic behavior in holographic displays through the activation of static elementary holograms. This research takes place in an ambitious concept of near-eye display, free of any focusing optical system. We investigate the dynamic addressing of holographic elements with a size of about 27 µm, distributed on centimeter-size samples. We project dynamic images with a resolution of 10 × 10 pixels. This first demonstration validates the ability to activate pixelated holograms with low cross talk, with an SNR of about 26. We project various images and analyze their rendering in an optical scheme consistent with visual behavior, using the integration time of a camera to mimic visual persistence. We demonstrate the image projection in a free space optical set-up using an SLM. This demonstration may pave the way to further potential developments implementing photonic integrated circuits inside the display.
