Abstract

We report on HoloTile, a new approach to speckle-reduced and rapidly generated holograms. By way of ananalytical approach to Gaussian beam shaping, we modify the Point Spread Function (PSF) of a holographicsystem into flat-top squares. The width of each flat-top output “pixel” is determined from the inter-spectraldistance arising from designed tiling on a Spatial Light Modulator (SLM). The resultant hologram consists ofthe product of a once-calculated PSF shaping hologram and a tiled object hologram. With HoloTile, we achievespeckle-reduced reconstructions and extremely fast hologram generation, due to the reduced resolution of theobject hologram.
