HoloTile is a patented computer generated holography approach with the aim of reducing the speckle noise caused by the overlap of the non-trivial physical extent of the point spread function in Fourier holographic systems from adjacent frequency components. By combining tiling of phase-only of rapidly generated sub-holograms with a PSF-shaping phase profile, each frequency component—or output ‘pixel’— in the Fourier domain is shaped to a desired non-overlapping profile. In this paper, we show the high-resolution, speckle-reduced reconstructions that can be achieved with HoloTile, as well as present new HoloTile modalities, including an expanded list of PSF options with new key properties. In addition, we discuss numerous applications for which HoloTile, its rapid hologram generation, and the new PSF options may be an ideal fit, including optical trapping and manipulation of particles, volumetric additive printing, information transfer and quantum communication.

HoloTile 光引擎：新的数字全息模式和应用

HoloTile 是一种获得专利的计算机生成全息方法，旨在减少由于傅里叶全息系统中相邻频率分量的点扩散函数的重要物理范围重叠而引起的散斑噪声。通过将快速生成的亚全息图的仅相位平铺与 PSF 整形相位轮廓相结合，傅立叶域中的每个频率分量（或输出“像素”）被整形为所需的非重叠轮廓。在本文中，我们展示了使用 HoloTile 可以实现的高分辨率、斑点减少的重建，并提出了新的 HoloTile 模式，包括具有新关键属性的扩展的 PSF 选项列表。此外，我们还讨论了 HoloTile、其快速全息图生成和新的 PSF 选项可能非常适合的众多应用，包括光学捕获和粒子操纵、体积增材打印、信息传输和量子通信。
