Augmented reality (AR) display, which superimposes virtual images on ambient scene, can
visually blend the physical world and the digital world and thus opens a new vista for human …

Abstract In 1948, Dennis Gabor proposed the concept of holography, providing a pioneering
solution to a quantitative description of the optical wavefront. After 75 years of development …

Holography provides access to the optical phase. The emerging compressive phase
retrieval approach can achieve in-line holographic imaging beyond the information-theoretic …

Spatiotemporal vortices of light, featuring transverse orbital angular momentum (OAM) and
energy circulation in the spatiotemporal domain, have received increasing attention recently …

Projecting high-quality three-dimensional (3D) scenes via computer-generated holography
is a sought-after goal for virtual and augmented reality, human–computer interaction and …

With the explosive growth of mathematical optimization and computing hardware, deep
neural networks (DNN) have become tremendously powerful tools to solve many …

In this paper, we review the existing approaches for vortex and vector beam sha** and
generation in the terahertz frequency range. The particular focus of this review is on the …

Spatiotemporal sculpturing of light pulses with sophisticated structures on demand is one
major goal of the everlasting pursuit of ultrafast information transmission and processing as …

The appearance of the first laser approximately 12 years after the invention of holography by
Gabor (1948) revolutionized the field of optical metrology. In fact, the invention of …

Photopolymers hold great promise for the preparation of transparent volume holographic
gratings (VHG), which are core optical elements in many application fields. To improve the …
