Readout fidelity of coaxial holographic digital data page recording in nanoparticle–(thiol–ene) polymer composites [PDF]
, 2016 We report on an experimental investigation of nanoparticle-concentration and thiol-to-ene stoichiometric ratio dependences of symbol error rates (SERs) and signal-to-noise ratios (SNRs) of digital data pages recorded at a wavelength of 532 nm in thiol ...

Holographic waveguides in photopolymers
Optics Express, 2019 The possibilities that offer the holographic optical elements for photovoltaic and "see through display" applications open new windows for holographic recording materials. In this sense, some specific characteristics are required for each particular application. Waveguides are one of the key elements for these applications. Photopolymers are one of the

Full-Color See-Through Three-Dimensional Display Method Based on Volume Holography
Sensors, 2021 We propose a full-color see-through three-dimensional (3D) display method based on volume holography. This method is based on real object interference, avoiding the device limitation of spatial light modulator (SLM).

One-step volumetric additive manufacturing of complex polymer structures. [PDF]
, 2017 Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new volumetric

Rheological Study of the Solidification of Photopolymer and Dispersed Nanotube Systems
Applied Rheology, 2011 We herein describe a set of rheological measurements that were carried out in order to characterize the solidification of photopolymers. The solidification depends on the length of time of exposure to UV light, and the intensity of that light, which ...
