Volumetric bubble display with holographic drawing and ultrasonic erasing
Hayasaki Yoshio

A volumetric display with microbubble voxels are three-dimensionally generated in a liquid by focused femtosecond laser pulses. A use of high-viscosity liquid slows down the movement of the microbubbles, and the volumetric graphics can be displayed. This “volumetric bubble display” has a wide viewing angle and simple refresh, and requires no addressing wires. An erasing of the bubble graphics using an ultrasonic vibrator has been also demonstrated.

Bo-An Lee Characteristics of Holographic Materials using Irgacure 784/EGPEA
Bo-An Lee;Je-Min Yang;Tzu-Chien Hsu;Wei-Hung Su

A fabrication approach using PMMA [poly(methyl methacrylate)] and EGPEA (ethylene glycol phenyl ether acrylate) for holographic materials is presented. Diffraction efficiencies with various thicknesses and concentrations are studied. A 3D image reconstructed by this hologram is presented as well.

Lung-Cheng Lee Fabrication of Dihedral Corner Reflector Arrays Using 3-D Printing
Cheng-Yu Li;Lung-Cheng Lee;Hsi-Fu Shih

The dihedral corner reflector array (DCRA) is an important device for floating image system. This paper applies the UV-curing 3-D printer to fabricate DCRAs for simplifying the complex processes. With the post-processing, 0.017 μm mean roughness could be achieved. Finally, the image formation verified the feasibility of the proposed method.

Stefan Petrov Large Scale Liquid Crystal Device with Graphene-based Electrodes
Stefan Petrov;Vera Marinova;Shiuan-Huei Lin;Chia Chang;Yi Lin;Ken Hsu

We demonstrate fabrication of large scale liquid crystal device with graphene-based electrodes. Various measurements wеre used to prove superior graphene properties. Photoalignment method was used instead of mechanical rubbing technique to preserve the graphene layer underneath. Modulation characteristics show similar behavior compared to the LC device using ITO contacts.

Han Sheng Xu Study on Volume Holographic Recording in Irgacure 784 doped PMMA Photopolymer at 532 nm
Han Sheng Xu;Shiuan Huei Lin;Vera Marinova;Ken Y. Hsu

This paper presents an investigation on the preparation and characterization of thick photopolymers for holograms recording at 532nm. Based on our previous research we develop a thick Irgacure 784 doped PMMA photopolymer with sensitivity at 532nm in this research. Material fabrication technique and the characteristics are reported.
