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.
