Lun-Kuang Lin Award Candidate Study on Volume Polarization Holographic Recording in PQ/PMMA for Optical Memory

Characteristics of recording polarization holograms in thick phenanthrenequinone-doped poly(methyl methacrylate) (PQ/PMMA) photopolymer are investigated. It is found that under paraxial approximation the circular polarization holograms provide a better distinction of the reading beams. A design of the holographic memory using circularly polarization recording configuration is described. Index Terms—holography, polarization hologram, data storage, photopolymer.

Andrey Vladimirovich Belashov Award Candidate Performance of phase tomography with a limited set of angle data

An experimental evaluation of the phase tomography accuracy with 18 hologram-projections is carried out. The heating process of an aqueous solution ofphotosensitiser under laser irradiation is used as an object under study. The reconstruction of temperature distribution using inverse Abel transformation and filtered back-projection algorithm and their comparison is performed.

Chin-Yu Liu Award Candidate Wide-field Digital Holographic Microscopy by combining telescopic optics and up-sampled Fresnel Reconstruction

A wide-field digital holographic microscopy (WF-DHM) system is proposed, which employs a telescopic architecture to achieve wide field-of-view and long working distance. Compared to the conventional microscopy, the sensor resolution can be improved to resolve the finer structures of object to be reconstructed from Fresnel hologram based on up-sampled technique.

Xin-Ji Lai Award Candidate Resolution enhancement by structured-illumination induced moiré effect in digital holographic microscopy

This study describes a structured-illumination induced moiré effect for resolution enhancement in digital holographic microscopy. The low-resolution moiré fringe and known regular structured pattern can be used to retrieve high-resolution information. The preliminary results indicate the feasibility in detection and enhancement of the low-resolution moiré fringe.

Hsi-Hsun Chen Award Candidate Bayesian inference computational imaging for super-resolution microscopy based on structured illumination

Structured illumination microscopy has been developed to break resolution limit of conventional microscopy in synthetic aperture fashion. In this paper, we develop an optimization framework based on Bayesian inference to enhance the performance of structured illumination microscopy. We demonstrate simulation results of this algorithm to improve resolution for reconstructed images.

Yu-Chih Lin Instantaneous imaging in directly pump-probe digital holographic microscopy

We propose and demonstrate a novel pump-probe measurement system by using digital holographic microscopy. The femtosecond Laser and CW Laser are used in directly pump-probe architecture, which achieve an instantaneous imaging when pumping just happened. The fast phenomenon of light-induced phase change thus be measured in a few femtoseconds.

Kuang-Che Chang Chien A Fuzzy-based approach for Shadow Detection in Phase-shifting Fringe Projection Profilometry

To increase accuracy of 3D reconstruction, interference of shadow should be excluded from images obtained by PSFPP before surface profile measurement. We propose an approach based on fuzzy logic analysis with three features, namely darkness, consistency and flatness, to efficiently and accurately detect shadow areas in a four-step PSFPP system.

Chen Chu Lung Color Pattern Recognition Based on CIELuv Color Space by Using Simulated Annealing on Liquid Crystal Device

This research uses the concept of simulated annealing to design the near optimal quantized reference function, and to combine with a Mach-Zehnder joint transform correlator (MZJTC). We transform a color image into three CIELuv color space components for identifying the different views of the target. From simulation results, the optoelectronic pattern recognition system with simulated annealing algorithm shows a good optimization capability.
