The random phase method and quadratic are most widely used in the generation of non-iterative holograms. However, former leads to reconstruction being severely disturbed by speckle noise, with serious loss detailed information, latter contaminated ringing artifacts. To solve these problems, we present a novel, best our knowledge, capable generating holograms, hereafter referred as hybrid-phase-only holograms (HPOHs). Our proposal is use weight factor combine generate hybrid mask. mask then...
The controllable preparation of spherical micro/nano particles various materials has been achieved via the technology laser synthesis and processing colloids (LSPC) recently. However, there is limited in situ research on evolution processes nanoparticles photothermal transient environments, such as solid-state crystal transformations changes state, which limits understanding application LSPC. Photoacoustic (PA) signals are sensitive to optical, thermal elastic properties medium, can be used...
As artificially designed two-dimensional (2D) arrays of subwavelength nanostructures, metasurfaces provide a new avenuefor the design static planar optics. However, one would prefer dynamic modulation metasurface in event practical applications. potentially important technique for information security, meta-holographic encryption has characteristics pixels, precise control, and high safety factor. In this paper, by integrating birefringent liquid crystals (LCs) with all-dielectric...
Color holographic display has been a research hot in many years, since it huge applications the field. In this paper, we employ laser direct write lithography system, that feature of high-resolution drawing and high-speed drawing, to make color computational holograms with different pixel numbers pitches. Based on method spatial division, optical experimental system is built, diffractive elements (DOEs) are fabricated by writing technology realize display. The results verify feasibility method.
