HANEDA - Holographic Near Eye Display
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.
