“…Both examples clearly show that our design approach allows finding new and desirable SVSL designs with a significantly improved performance and wearability. Manufacturing our hybrid SVSL designs requires advanced manufacturing techniques such as holographic printers [24][25][26] that are capable of creating arbitrary HOE configurations. Recent improvements in holographic materials suggest that our simulated diffraction efficiencies can be realized experimentally [27,28].…”

In this contribution, we investigate hybrid single vision spectacle lenses (SVSLs) consisting of holographic optical elements (HOEs) embedded into a refractive lens. We evaluate the performance of two examples of hybrid SVSLs in terms of their distributions of spherical error (SPH error), astigmatic error (AST error) and transverse chromatic error (CE) over the lens surface, simulating the optical performance for the patient's rotating eye. We find that, particularly for high prescription values, hybrid SVSLs outperform their purely refractive counterparts in terms of CE with the additional benefit of reducing the lens thickness. As such, we show that hybrid refractive, holographic designs can be a viable alternative to purely refractive SVSLs for high prescription SVSLs.

“…The photopolymer was exposed by the interference fringes. We adopted the scanning-based exposure method called holographic printing [23][24][25][26][27][28][29] to realize spatially uniform diffraction efficiency of the holographic mirror. The photopolymer was mounted on a two-axes-motorized stage for scanning.…”

A holographic mirror is a reflection-type holographic optical element that works as an off-axis mirror. It realizes an upright see-through screen serving as a virtualimage display and virtual camera. Such screen enables to realize virtual-imagebased attractive applications like Pepper's ghost only with a thin optical system. This chapter describes the concept of a holographic-mirror-based virtual-image display and virtual camera, an experimental method for exposing the holographic mirror based on holographic printing, methods for dispersion compensation, and experimental results for the proposed virtual-image display and camera.

“…A hogel overlapping method for enhancing the lateral resolution of holographic stereogram was proposed by Hong et al [56]. The shifting distance of hogel was smaller than the hogel size, and the maximum number of recordable overlapped hogels depended on the dynamic range of the holographic recording medium.…”

Abstract:The synthetic holographic stereogram printing technique can achieve a three-dimensional (3D) display of a scene. The development and research status of the synthetic holographic stereogram printing technique is introduced in this paper. We propose a two-step method, an infinite viewpoint camera method, a single-step Lippmann method, a direct-write digital holography (DWDH) method and an effective perspective images' segmentation and mosaicking (EPISM) method. The synthetic holographic stereogram printing technique is described, including the holographic display with large format, the large field of view with no distortion, the printing efficiency, the color reproduction characteristics, the imaging quality, the diffraction efficiency, the development of a holographic recording medium, the noise reduction, and the frequency response analysis of holographic stereograms.
