Ging-rue Liu Opto and magneto dual imaging platform for rapid ex-vivo and in-vivo discrimination of tumors
Ging-rue Liu;Wen-Chun Wei;Jen-Jie Chieh

A novel dual-imaging model system integrating an optical camera and magnetic scanning superconducting-quantum-interference device (SQUID) biosusceptometry (SSB) was proposed. The simultaneous coregistration of low-field magnetic images of MNP distributions and optical images of anatomical regions enabled the tumor distribution to be determined easily and in real time.

CHANG FU-KAI Ultra-compact illumination system design for dual view capsule endoscope
CHANG FU-KAI;Sheu Ming-Jen;Pan Jui-Wen

We use two prescribed illumination distributions to compensate for the low relative illumination. In the optical simulation, we obtain an illumination uniformity of 67.86% and an efficiency of 33.45% for the front view area and an illumination uniformity of 74.92% and an efficiency of 19.32% for the back view area.

Tulsi Anna Optical Visualization and Morphological Analysis of Leaves using Spectral Domain Optical Coherence Tomography (SD-OCT)
Tulsi Anna;Sandeep Chakraborty;Chia-Yi Cheng;Arthur Chiou;Wen Chuan Kuo

Here, a non-destructive spectral domain optical coherence tomography (SD-OCT) system to monitor morphological changes in autumn phenology (senescence) of Acer serrulatum leaves was reported. Structural changes in the epidermis and thickness variation in palisade layer has been observed.This system has the potential to generate quality control in agricultural field.

Shi-Xuan Yang PSTD simulation of expending beam width with the presence of a scattering medium
Shi-Xuan Yang;Snow H. Tseng

We employ the pseudospectral time-domain (PSTD) simulation technique to model light distribution through the scattering media. To analyze the scattering characteristics of light, various factors are analyzed. Specifically, scattering medium consisting of diverse scatter sizes resulting in a different angular span of out-coming light.

Wen-Chun Wei Noninvasive, Biochemical Consumable-Free, and Fast Examination of Orchid Diseases
Wen-Chun Wei;Yen-Hsiang Wang;Kuan-Chieh Lee;Ming-Hsien Chiang;Shien-Kuei Liao;Jen-Jie Chieh

The spectrum analysis for the noninvasive examination of orchid virus is a challenge due to time-varied biological conditions of live individuals. In this work, two algorithm analysis were proposed to discriminate orchid diseases. The sensitivities are 77.5 % and 88 % for the calibration analysis and Gaussian decomposition analysis, separately.

Han Lee Here we model an acoustic wave source propagating out of needle by employing finite-difference time-domain simulation technique. To analyze phenomenon, various factors are analyzed, including wavelength of acoustic wave, speed of sound, density of medium and size of needle. Finally, simulation results are used to help analyze experimental measurements
