“…One of the foci of the ongoing research relate to chromaticity, polarization dependence and, particularly, imaging capabilities of 4G lenses. These issues are overcome due to the multitude of opportunities of customizing the performance features of 4G Optics [11,16], with optimum solutions for different application needs.…”

We will review the state-of-the-art of the Fourth Generation Optics-a planar optics rooted in LCD technology,-and the advance it has enabled in display, AR/VR, imaging, and other critical modern technologies beyond displays. The review will lead to the conclusion that the technology is mature for many applications offering the most versatile and efficient techniques for controlling light with truly flat, thin film, achromatic, and high quality optical systems produced at low manufacturing cost inherent to LCDs.

“…These are likely to be applied to beam steering [3][4][5][6], imaging [7,8], and near-eye displays [9,10], as well as 3D displays and virtual reality/augmented reality (VR/AR) [4,[11][12][13][14]. A PG is a diffractive optical element in which the in-plane anisotropic orientation varies linearly along the surface and the magnitude of anisotropy is constant [15][16][17][18][19][20][21][22][23]. It is fabricated by methods such as optical orientation by two-flux interference exposure [24], micro-rubbing [25,26], photomasking [27], and direct beam writing [8,28].…”

Photoresponsive photoalignable liquid crystalline polymers composed of phenyl benzoate terminated with N-benzylideneaniline were evaluated. These polymers are capable of axis-selective photoreaction, photoinduced orientation, and surface relief grating formation. Polarization holography using an He-Cd laser beam at a wavelength of 325 nm demonstrated the formation of a surface relief grating with a molecularly oriented structure based on periodic light-induced reorientation and molecular motion. Electrical switching of diffracted light using an electric field response of twisted-nematic cell containing a low-molecular-weight liquid crystal in combination was also demonstrated.

“…The multifunctional DOEs comprise imaging, shaping, and multiplexing functions in a single binary surface relief layer. Roberts et al [21] found that the combination of cycloidal diffractive waveplates (CDWs) and polarization volume gratings (PVGs) results in high-efficiency polarization-insensitive diffraction, which can be used in diffractive waveplate lenses. Furthermore, a polarization-independent liquid crystal Pancharatnam-Berry (PB) lens system [22] has been developed.…”

Hologram technology has attracted a great deal of interest in a wide range of optical fields owing to its potential use in future optical applications, such as holographic imaging and optical data storage. Although there have been considerable efforts to develop holographic technologies using conventional optics, critical issues still hinder their future development. A metasurface, as an emerging multifunctional device, can manipulate the phase, magnitude, polarization and resonance properties of electromagnetic fields within a sub-wavelength scale, opening up an alternative for a compact holographic structure and high imaging quality. In this review paper, we first introduce the development history of holographic imaging and metasurfaces, and demonstrate some applications of metasurface holography in the field of optics. We then summarize the latest developments in holographic imaging in the microwave regime. These functionalities include phase- and amplitude-based design, polarization multiplexing, wavelength multiplexing, spatial asymmetric propagation, and a reconfigurable mechanism. Finally, we conclude briefly on this rapidly developing research field and present some outlooks for the near future.
