摘要: A printing device (106) includes a laser source and a LCOS-SLM (Liquid Crystal on Silicon Spatial Light Modulator). The printing device generates a laser control signal and a LCOS-SLM control signal. The laser source (110) generates a plurality of incident laser beams based on the laser control signal. The LCOS-SLM (112) receives the plurality of incident laser beams, modulates the plurality of incident laser beams based on the LCOS-SL M control signal to generate a plurality of holographic wavefronts (214,216) from the modulated plurality of incident laser beams. Each holographic wavefront forms at least one corresponding focal point. The printing device cures a surface layer or sub-surface layer (406) of a target material (206) at interference points of focal points of the plurality of holographic wavefronts. The cured surface layer of the target material forms a three-dimensional printed content.

摘要: A printing device (106) includes a dynamic holography printing application configured to generate a laser control signal and a LCOS- SLM (Liquid Crystal on Silicon Spatial Light Modulator) control signal based on a two-dimensional content corresponding to a lithography mask. A laser source (110) generates a plurality of incident laser beams based on the laser control signal. A LCOS-SLM (112) modulates the plurality of incident laser beams based on the LCOS-SLM control signal, generates a plurality of holographic wavefronts (214,216), each holographic wavefront forming at least one corresponding focal point. The LCOS-SLM generates a plurality of distinct focused light field regions (506,508,510) at interference points of focal points of the plurality of holographic wavefronts. The plurality of distinct focused light field regions correspond to the two-dimensional content.

摘要: A display system comprising a data provider, a phase-only spatial light modulator (SLM) 701 and a second cylindrical lens 750. The data provider provides first data to the SLM, wherein the first data corresponds to a first cylindrical lens implemented as lensing data in holographic data supplied to the SLM. The first cylindrical lens has optical power in a first direction. The spatial light modulator receives the holographic data, wherein the spatial light modulator spatially-modulates the received light in accordance with the holographic data. The second cylindrical lens, which may be a physical lens, receives the spatially-modulated light from the spatial light modulator and performs a one dimensional Fourier transform of the received light in a second direction, orthogonal to the first direction. The arrangement is intended to reduce intense unwanted zero-order (DC order) light from the reconstructed image, such that it is limited to only part 707 of the holographic reconstruction plane 705.
