Optimized Design of Multi-Function Optical Microscope System
Wei-Chung Wang,

in micro-electro-mechanical systems (MEMSs) because of their non-contact, whole-field, remote-sensing and high-resolution characteristics. Microscope has been widely employed to measure micro engineering objects. Scanning white-light interferometer (SWLI) is a fast and high vertical resolution instrument to measure three-dimensional (3D) shape of engineering objects of high aspect ratio. In the past, Mirau SWLI was popularly adopted in microscopic systems due to its modularized objective lens. Since a Linnik SWLI does not need any optical components in front of the objective lens, higher numerical aperture can then be achieved. In addition, Linnik SWLI has higher lateral resolution than that of Mirau SWLI.

Yung-Hsiang Hsu Award Candidate Linear Polarization Independent Liquid Crystal Lens Array with Self-Aligned Lithography Process
Yung-Hsiang Hsu,Chia-Rong Sheu,

Polarization-independent liquid crystal lens arrays fabricated with self-aligned dual hole-patterned electrodes is demonstrated. A middle glass substrate with self-aligned hole-patterned electrodes on both surfaces combines two other glass substrates to form a composite lens array composed of two orthogonal homogeneous liquid crystal cells. The fabricated LC lens arrays show electro-optical features of tunable focuses and polarization-independence.

Chia-Yuan Chang Award Candidate Wavefront Sensorless Adaptive Optics in Temporal Focusing Multiphoton Microscopy
Chia-Yuan Chang,Li-Chung Cheng,Shean-Jen Chen,

By combining the multiphoton excitation mechanism and temporal focusing technique, temporal focusing multiphoton microscopy has widefield optical sectioning ability and already demonstrates the potential for widely applications. However, temporal profile distortions reduce excitation efficiency and degrade image quality. In order to compensate the distortions, a wavefront sensorless adaptive optics system (AOS) was integrated. With the AOS correction, not only the axial excitation symmetrically is refocused, but the axial resolution with two-photon excited fluorescence (TPEF) intensity is also maintained.

Sheng-Yi Lee Award Candidate Planar micro-optic concentrator
Sheng-Yi Lee,Che-Wen Chiang,Yu-Chung Su,Jui-Wen Pan,

In this study, we optimize the planar micro-optic concentrator by the optical simulation. The half acceptance angle of the planar micro-optic concentrator with a 300X concentration is 0.115 degrees and 0.275 degrees, and the optical efficiency is 81.23% and 71.92%, respectively.

Pei-Han Liao Award Candidate I-shaped plasmonic filter for three primary colors
Pei-Han Liao,Chun Yen Liao,Chih-Ming Wang,Din Ping Tsai,

In this paper, we propose a free-space plasmonic filter based a 1D I-shaped metallic structure. The I-shaped structure supports three localized surface plasmon resonance modes which locate at the wavelength close to the three primary colors. The three resonance modes present omnidiretional resonance properties due to the localized nature.
