Sin-Yi Huang In situ monitoring of femtosecond laser induced cavitation with lock-in signal amplification

Femtosecond laser can achieve multiphoton plasma-induced ablation in bio-tissues and cells. In this study, we add a He-Ne laser system to probe ablation processing and the very weak cavitation signal is enhanced by using a lock-in amplifier. By analyzing the probe signals, we can further know some information such as material ablation threshold, and so on.

Lin Yu Cheng A Reflection-Type Fiber-Optic Sensor Based on Surface Plasmon Resonance

A reflection-type (R-type) fiber-optic sensor probe based on surface plasmon resonance (SPR) technology is demonstrated. The maximum SPR efficiency is about 45.8% at resonant wavelength 671 nm and 46.2% at 0.696 nm for DI water and alcohol, respectively. The R-type sensor shows better performance in both DI water and alcohol detection than the conventional transmission-type (T-type) sensor.

YU-YIN LU Study on the Optical-fiber based on Glucose Sensor by using Heterodyne Interferometry

This study demonstrated a novel fiber-type glucose sensor which immobilized the glucose oxidase (GOx) on the no-core fiber (NCF). The glucose will convert to gluconic acid and affect the phase difference between p- and s- polarizations coming from the total internal reflection (TIR) at the interface between NCF and testing sample. The phase variation can be measured precisely by heterodyne interferometer. According to the results, the resolution and sensitivity of the proposed sensor will affect by the length of the NCF. The proposed sensor with 3 cm in length of NCF exhibited high sensitivity and resolution which can be approximately 0.01142 (deg/mg ) and 0.032 (mg/dl), respectively. Besides, the volume of the test sample is less than 1 ml and response time is shorter than 2 sec.

Neuromuscular electrical stimulation (NMES) are often used to prevent muscle atrophy generally, while the strength and work are confirmed by doctor's experience. In our study, we use near-infrared spectroscopy (NIRS) to measure tissue oxygenation changes within electrical stimulation. To quantify the influence of NMES is helpful on doctors’ diagnosis and has an opportunity to reduce the pain from NMES.

Pavel Rogov Mechanism of femtosecond laser radiation influence on skin

In this paper we presented a mathematical model that describes the linear and nonlinear processes arising from action of femtosecond laser radiation on the skin. We have completed the solution of the equations describing the dynamics of the electron and phonon subsystems. Methods and numerical simulation have shown that threshold damage to the skin under femtosecond pulses radiation increases with decreasing pulse duration. The results of this work can be used to create a laser safety standard for femtosecond laser systems.
