TL;DR: Spatial partitioning of the spatial light modulator is proposed to perform mosaic delivery of exposures at primary colors for seamless reconstruction of a white light viewable color hologram.
Abstract: The holographic wavefront printer decodes the wavefront coming from a three-dimensional object from a computer generated hologram displayed on a spatial light modulator. By recording this wavefront as an analog volume hologram this printing method is highly suitable for realistic color 3D imaging. We propose in the paper spatial partitioning of the spatial light modulator to perform mosaic delivery of exposures at primary colors for seamless reconstruction of a white light viewable color hologram. The method is verified for a 3 × 3 color partitioning scheme by a wavefront printer with demagnification of the light beam diffracted from the modulator.

TL;DR: In this paper, light recycling films comprising an array of parallel ridges and grooves that form prisms that selectively reflect or transmit light are used in displays that include spatial light modulators comprising a plurality of pixels.
Abstract: Various embodiments comprise light recycling films comprising an array of parallel ridges and grooves that form prisms that selectively reflect or transmit light. In some embodiments, the light recycling film may be used in displays that include spatial light modulators comprising a plurality of pixels. The light recycling film can limit the field-of-view of the display and enhance the luminance within that field-of-view. Various embodiments comprising multiple arrays of ridges and/or grooves can enhance uniformity of illumination of the pixels in the spatial light modulator and reduce Moire effects.

TL;DR: This work demonstrates a vector HOT with arrays of digitally controlled Higher-Order Poincaré Sphere (HOPS) beams, employing a simple set-up using a spatial light modulator and showing that each beam in the array can be manipulated independently and set to an arbitrary HOPS state, including replicating traditional scalar beam HOTs.
Abstract: The invention of optical tweezers almost forty years ago has triggered applications spanning multiple disciplines and has also found its way into commercial products. A major breakthrough came with the invention of holographic optical tweezers (HOTs), allowing simultaneous manipulation of many particles, traditionally done with arrays of scalar beams. Here we demonstrate a vector HOT with arrays of digitally controlled Higher-Order Poincare Sphere (HOPS) beams. We employ a simple set-up using a spatial light modulator and show that each beam in the array can be manipulated independently and set to an arbitrary HOPS state, including replicating traditional scalar beam HOTs. We demonstrate trapping and tweezing with customized arrays of HOPS beams comprising scalar orbital angular momentum and cylindrical vector beams, including radially and azimuthally polarized beams simultaneously in the same trap. Our approach is general enough to be easily extended to arbitrary vector beams, could be implemented with fast refresh rates and will be of interest to the structured light and optical manipulation communities alike.

TL;DR: The phase-mode SLM implements spatial distribution of phase retardation required in the parallel phase-shifting digital holography and can also compensate dynamically the phase distortion caused by optical elements such as beam splitters, lenses, and air fluctuation.
Abstract: Parallel phase-shifting digital holography using a phase-mode spatial light modulator (SLM) is proposed. The phase-mode SLM implements spatial distribution of phase retardation required in the parallel phase-shifting digital holography. This SLM can also compensate dynamically the phase distortion caused by optical elements such as beam splitters, lenses, and air fluctuation. Experimental demonstration using a static object is presented.

TL;DR: In this paper, a maskless patterning system with capability for selecting rapidly among a plurality of projection lenses mounted on a turret is presented, which provides the ability to rapidly select multiple choices for resolution and enables optimization of the combination of the imaging resolution and exposure throughput, making possible cost effective fabrication of microelectronics packaging products.
Abstract: A versatile maskless patterning system with capability for selecting rapidly among a plurality of projection lenses mounted on a turret. This provides the ability to rapidly select multiple choices for resolution and enables optimization of the combination of the imaging resolution and exposure throughput, making possible cost-effective fabrication of microelectronics packaging products. A preferred embodiment uses a digital micromirror device array spatial light modulator as a virtual mask. Another preferred embodiment use multiple closely spaced digital micromirror device array spatial light modulators to enhance throughput.
