A review of fast speed solid state KTN beam deflectors
Shizhuo Yin

n this paper, we provide a brief review on fast speed solid state beam deflectors based on potassium titanalate niobate (KTN) electro-optic (EO) crystals. Different types of beam deflection mechanisms are addressed, including both the conventional uniform electric field but non-uniform geometric shape (e.g., prism shape) enabled beam deflection as well as non-conventional non-uniform electric field enabled beam deflection. The non-uniform electric field can be realized by several different approaches such as space-charge-controlled beam deflection, temperature gradient controlled beam deflection, and composition gradient controlled beam deflection. The advantages and limitations of each approach are discussed. Furthermore, we present the method of how to realize nanosecond speed, large aperture KTN beam deflection by overcoming the electric field induced phase transition. Finally, we discuss a variety of killer applications of fast speed solid state KTN beam deflectors, including high speed high resolution imaging and display, high speed 2D/3D printing, massive high speed optical storage, as well as all-solid state holographic systems.

Tianlong Man Award Candidate Fluorescence Digital Holographic Microscopy with Computation Aberration Correction
Tianlong Man;Yuhong Wan;Dayong Wang

Computational adaptive optics is implemented in fluorescent imaging system by preserving the phase of optical aberrations using self-interference digital holography. Optimization process on virtual pupil of the reconstructed complex-valued image enables guide-star-free aberration correction. The validity of the proposed method is demonstrated by simulations and experiments.

Yan-Xun Li Award Candidate Contrast-encoded patterns for phase-shifting projected fringe profilometry
Yan-Xun Li;Sih-Yue Chen;Nai-Jeng Cheng;Wei-Hung Su

Most fringe-projection methods based on phase-shifting techniques require additional projected patterns to identify the fringe order for phase unwrapping. The total number of projections is usually more than that used for phase-extraction. In this paper, the fringe patterns used for phase-extraction can be analyzed for unwrapping directly.

Yang Kun Chew Award Candidate Image Fidelity Improvement in Transmission-type Digital Holographic Microscopy via Optical Phase Conjugation
Yang Kun Chew;Huang Tian Chan;Min Tzung Shiu;Chi Ching Chang

Optical phase conjugation technique has been employed to suppress scattering noise of the object beam, prior to the recording stage in digital holographic microscopy. Image fidelity of reconstructed images has been improved significantly.

Keng-Chang Hsu Award Candidate Design of See-through Edge-lit Computer-Generated Hologram for Augmented Reality
Keng-Chang Hsu;Shiuan Huei Lin;Vera Marinova;Ken Y. Hsu

In this paper, we present a see-through edge-lit holographic display for AR applications. The design concept and preliminary experimental result will be shown and discussed.

Sheng-Chi Liu Award Candidate Complex Binary-amplitude CGH Displays by using an Amplitude-only SLM
Sheng-Chi Liu;Daping Chu

A holographic display system for complex binary-amplitude CGHs using a single amplitude-only SLM combined with a random phase mask is investigated. The simulation results show that it can reconstruct the target image with a minimized conjugate part and the full size of the SLM.
