High Resolution Multiview Holographic Display Based on the Holographic Optical Element
Limited by the low space-bandwidth product of the spatial light modulator (SLM), it is difficult to realize multiview holographic three-dimensional (3D) display.

Dual-View Integral Imaging 3D Display Based on Multiplexed Lens-Array Holographic Optical Element
We propose a dual-view integral imaging 3D display based on a multiplexed lens-array holographic optical element (MHOE). A MHOE is a volume holographic optical element obtained by multiplexing technology, which can be used for dual-view integral imaging ...

Planar Black Holes and Entanglement Entropy in Analog Gravity Models [PDF]
Via constructing an explicit Lagrangian for which the perturbation equations are analogs of a scalar field propagating in a planar black-hole space–time, it is found that all planar black holes conformal to a Painlevé–Gullstrand-type line element can be ...

An efficient and wide angle coupling of light to a thin film holographic optical element [PDF]
In this paper, a new method is proposed to achieve wide-angle and efficient coupling of light into a thin film, holographic optical element (HOE). The coupling is based on diffraction of light (the probe beam) by a holographic element.
