Holographic optical system to copy holographic optical elements

open access: yes, 1991
A holographic system formed by two holographic lenses that, when working with white light, allow selection of a particular wavelength is presented. If adequate spatial and temporal coherence conditions are obtained, it is possible to copy holographic optical elements (HOEs) with partially coherent light by using optical systems formed by holographic ...

Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology

open access: yesInfoScience, EarlyView.
Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored

Projection-Type Holographic Display With Observation Area Expanded Using Time-Division Reproduced Light Generation System

open access: yesIEEE Access
Projection-type holographic displays are three-dimensional (3D) displays that utilize computer holography. These displays consist of a projection lens and a transparent holographic optical element (HOE) with off-axis concave mirror phase distribution and

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

open access: yesJournal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.

Curved holographic optical elements and applications for curved see-through displays

open access: yesJournal of Information Display, 2019
Holographic optical elements (HOEs) have been used as important tools for implementing augmented reality (AR) and see-through displays because they are transparent and thin.

Combining the Underwater Vision Profiler 6 with sediment traps to measure in situ velocity of marine particles

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.
