Abstract

HoloTile is our novel and recently patent-filed approach [1,2] to obtain very fast reconfigurable and strongly speckle-reduced digital holography. Using HoloTile we have experimentally demonstrated more than 90 % photon-efficient phase-only projected dynamic and static far field diffraction both with and without a lens. A key aim for inventing and innovating HoloTile has been to effectively solve the challenge of rapid and speckle-free coherent or semi-coherent light sculpting without the need for time-averaging techniques - a challenge that exists in several fields of optics and photonics. In particular, HoloTile provides four new unique key features as CGH-modality for high-resolution spatial light modulators, reconfigurable DOEs or new meta-surface MOEs: • A 100x speed improvement over standard CGH-modalities • Substantial speckle reduction by matched tiling and PSF-shaping • Real-time dynamic and output 'pixel' discretized digital holograms • Lens-free scaling or zoom by software adapted HoloTile phase-encoding.
