Ching-Hsiang Chan Using off-specular microscopic imaging ellipsometry for biosensing aided by 1D reflection grating
Ching-Hsiang Chan;Yu-Da Chen;Ming-Lin You;Pei-Kuen Wei;Yia-Chung Chang

We performed spectroscopic ellipsometry and microscopic imaging ellipsometry measurements of the off-specular reflection signals of objects on various reflection gratings. We show that spectral ellipsometry in off-specular reflection mode can be used as an effective method for sensitive optical detection of foreign objects, which is especially useful for biosensing.

Sunil Vyas Multiplane Edge Contrast Enhancement Imaging Using Forked Shaped Defocus Grating
Sunil Vyas;Chen Yen Lin;Yuan Luo

We report on the implementation of spiral phase contrast imaging at multiple planes using forked-shaped defocus grating. The dual function of grating helps in simultaneous generation of multiple edge enhanced images corresponding to different depths. Present method is simple, direct and is applicable to coherent and incoherent imaging system.

Chen Jia Xuan Automated Identification of Low Dose Computed Tomography Subtle Nodules
Chen Jia Xuan

In this study, we designed a computer-aided diagnostic system. Calculate the characteristic parameters of the nodule image and put them into the inverted neural network to determine the results. The accuracy is 75% with true positive 75% and true negative 75%.

Wei-Han Hung Differentiation of esophageal cancer cells by multiphoton fluorescence lifetime imaging microscopy (M-FLIM)
Wei-Han Hung;I-Chen Wu;Wei-Chung Chen;Ming-Tsang Wu;Chie-Tong Kuo;Fu-Jen Kao;Guan-Yu Zhuo

Esophageal cancer has fatally attacked human health over the past few decades. Here we present a novel quantitative analytical tool that can be used to discriminate among the various types of esophageal cancers prior to diagnosis. Our cancer cell classification results were confirmed using multiphoton fluorescence lifetime imaging microscopy.

Yu-Cheng Lin Design of LMR Based Sensor with ITO-Coated POF
Yu-Cheng Lin;Shang-chen Wei;Wen-xiao Luo;Yongjie Xu;Shuting Xu;Bo-yu Lin

The design of plastic optical fiber sensor based on lossy-mode resonance was studied. The sensing device is a D-shaped plastic optical fiber and a thin-film layer of ITO is deposited. The influence of the thickness of optical fiber and ITO on the sensitivity is evaluated theoretically.

YI-JU LO Hydrogen peroxide concentration measurement by polarization spectral analysis technique
YI-JU LO;Te-Yu Chiang;Yu-Jen Chen;Cheng-Chih Hsu

This study demonstrated the H2O2 concentration measurement with polarization spectrometry. Based on the experiment results, the absorbance of the product is related to the H2O2 concentration and polarized state of the incident light. The best sensitivity and resolution can be reached 1478 absorbance/% and 1.3510-5 %, respectively.
