Optimization of Light-Emitting Diode Mosquito Trap System Effectiveness
Chang JUI Chen

A mosquito-collecting component that can be externally attached to the air inlet of a light-emitting diode mosquito-trapping system was developed to optimize the efficiency of the mosquito-trapping lamp and increase mosquito-trapping capacity. Used the three-dimensional computer-aided design software SolidWorks to build the system Finally,data obtained, mosquito-trapping efficiency was optimized.

LED-based Automatic Fringe-resolved Autocorrelator
Chia-Yuan Chang;Xin-Li Lee;Jui-Chi Chang

The fringe-resolved autocorrelator is a widely adopted system for measuring the
ultrashort pulse characteristic. Based on the nonlinear optical response of the light-emitting
diode (LED), we can build a low-cost fringe-resolved autocorrelator. The automation can be
achieved by synchronizing the reference beam movement and the photocurrent detection based
on LabVIEW.

Shack-Hartmann Wavefront Sensor for Broadband Wavelength Range
Cheng-Jung Yang;Chia-Yuan Chang;Yu-Cheng Wu

The Shack-Hartmann wavefront sensor (SHWS) is a powerful tool to monitor the optical wavefront and decomposed into Zernike modes in real time. We have shown that using the center detection algorithm doesn’t only improve the analysis accuracy but also allow the wavelength detection range cover from ultraviolet to visible band.

Sensing Measurement of Hollow-Core Photonic Crystal Fiber Sensor
Jung-Sheng Chiang;Tsung-Han Chin;Jeng-Chian Lai;Jia-Ming Syu;Nai-Hsiang Sun

The sensing properties of negative curvature hollow-core photonic crystal fiber sensor by measurement are presented. The spectrum of the hollow-core photonic crystal fiber sensor is from sensing to different materials. The power loss is decreased as the refractive index of materials increased and having flattened variation at 1545-1560 nm wavelengths.
