Kang Hwi Song, a researcher at Faculty of Electronic Engineering, and his research group have succeeded in manufacturing an Optical Passingtime Detector using infrared optical technology and Zigbee wireless communication and are expanding their achievements. This detector ensures speed measurement accuracy of 0.01s in a 30-meter section which is an important item in selecting and training reserve footballers.
As it is portable, it can be taken for camping drill and also be used in outdoor conditions with high illuminance as well as indoors. Moreover, it offers high stability and accuracy of speed measurement. The range of time measurement is 0~100s and the measurement accuracy is 0.01s.
