Abstract

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