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.
