Multiple input multiple output (MIMO) visible light communications – Design and Testing
Le-Minh Hoa

Office and home lighting sources are currently evolving through the traditional fluorescent and incandescent sources to the modern energy saving light bulbs and now white light emitting diodes (LEDs). This trend has been spurred on through global awareness of the necessity for reducing the size of our carbon footprint. The introduction of solid state LED lighting has attracted the attention of communications engineer’s worldwide, enabling the achievement of the dual functionality of room illumination whilst simultaneously transmitting wireless data via visible light communication (VLC). This technology offers advantages over the traditional wireless radio frequency (RF) communications system because of the signal quality, license free spectrum it occupies and data security. In order to achieve moderately uniform illumination within homes and offices, it is a common practice to use multiple LED lighting units. From the VLC viewpoint, these lighting units can be used as multiple transmitters each transmitting independent data streams, which forms the multiple-input-multiple-output (MIMO) system. MIMO VLC technique for visible light communications (VLC) facilitates higher data rate thanks to parallel data transmission.The talk will discuss on MIMO VLC technology, including system and sub-system design and testing, and further extend to the security, channel estimation features and camera-based VLC.

Measuring the randomness of light fields
Chung-Hao Tien

Image formation is a random process. The theory of random processes deals with the mathematical description of temporal (or spatial) functions having a structure that cannot be determined in advance. For optics, the wave amplitude emitted by any practical source has properties that change with time and space to some degree. Based on the Van Cittert–Zernike theorem, in this work we reviewed and examined the basic concepts underlying the theory of the coherence phenomena of light fields through a double-slit and grating interference experiment. This work would be expected to have an impact in the realm of lithography, information optics or partial coherence imaging analysis.

Yan-Ting Shen Fiber Bragg Grating Interrogation System for Real Time Angular Velocity and Vibration Monitoring
Yan-Ting Shen;Sin Rong Yang;LEE TING CHENG;Ming Chang Shih

We demonstrated a fiber Bragg grating (FBG) signal interrogation system which can achieve angular velocity and mechanical vibration measurements in real time. Real time vibrational measurement as small as 1 Hz and minimum angular velocity measurement of 0.105 rad/s (1 rpm) can be achieved by this system

JING-HENG CHEN Generating of 2×1 Outputs for Cylindrical Vector Beams
JING-HENG CHEN

A design for generating 2×1 outputs of cylindrical vector beams is proposed. With coherent superposition of two orthogonal Hermite–Gaussian modes, two types of output for radially and azimuthally polarized beams can be achieved. The proposed design has a simple and compact structure which has considerable potential in interferometric applications.

Pei-Hsuan Yang Effect of lenses color on maximum permissible exposure-limit of retina
Pei-Hsuan Yang;Meng-Han Wang;Tsai-Chen Li;Wen-Jun Lin;Ming-Li Chou;Mei-Lan Ko;Jwo-Huei Juo

Prolong exposure of intense indoor or outdoor light will damage human eyes. We investigate if wearing sunglasses or tinted lenses can effectively reduce the damage. We found that yellow tinted lenses will provide retina the best protection among seven tinted lenses studied as visual clarity is taken into consideration.

YU JIE CHEN Correlations between Tunable Wavelength and Distribution of Mode Spectrum in the Direct Filtering of Fabry-Perot Laser Diode
YU JIE CHEN;Han Yang Meng;Te Kung Tsu

The single- wavelength can be obtained by direct filtering of the mode spectrum of Fabry-Perot laser diode (FPLD). The different mode spectra controlled by the different dc-biased currents of the FPLD will generate the different tuning wavelength range, peak wavelength, and side mode suppression ratio (SMSR).

Yu-Jen Chen Effect of Color Printing Materials on Human Eyes
Yu-Jen Chen;Yu-Rou Cheng;Da-Hsing Kuan;Ming-Li Chou;Me-Lan Ko;Jwo-Huei Jou

We present here the effect of color printing materials on retina and reading clarity especially under the reflected light from a white LED. We found that the uncoated board paper shows the least damage to retina and provides the highest clarity among the three types of paper investigated.

Cho-Chun Chiang DC and AC Characterization of InP-Based SAGCM-Structure Avalanche Photodiode
Wen-Jeng Ho;Cho-Chun Chiang;Jheng-Jie Liu

DC and AC characteristics of InP-based SAGCM-structure avalanche photodiode were characterized. The dark current of 44.2 nA (63.9 nA), capacitance of 1.083 pF (1.08 pF), multiplication gain of 6.2 (11) at 0.9 VBR (0.95 VBR), and the f3-dB.MAX of 2.7 GHz and gain-bandwidth product of 47.5 GHz are obtained.

Wen-Chun Wei A Portable and Economic Fluorescence Instrument for Nondestructive Examination of Biochemical Materials
Wen-Chun Wei;Kuan-Chieh Lee;Yen-Hsiang Wang;Ming-Hsien Chiang;Shien-Kuei Liao;Jen-Jie Chieh

Because currently commercial florescent spectrometers are expensive and inconvenient, this work has developed a portable and economic platform for noninvasive examination. Besides the optical mechanism, the major measurement of some chlorophyll viruses was the harmless green light, instead of the common and damaging UV/blue light as the excitation light.

Hui-Yueh Chou Analysis of Top Plate of Guitar Using Laser Displacement Sensor and Microphone
Hui-Yueh Chou;Chong-Wei Kao;Yi-Nong Jhou;Chii-Chang Chen

We compare the acoustic response of a folk guitar using laser displacement sensor and microphone. The frequency spectra of the measurement results can be obtained for both methods. The results show that the different locations at the body of guitar might contribute the vibration of different notes.
