摘要： An optical touch apparatus and a touch method thereof are provided. A plurality of light sensing units are disposed between a first scanning light source and a second scanning light source, wherein the light sensing units, the first scanning light source and the second scanning light source are disposed at a same side of a touch surface. A touch position of an input tool is determined according to an intensity of a scattered light generated by an input tool and sensed by the light sensing units and generated when a first scanning beam and a second scanning beam scan the input tool.

摘要： A laser scanning device and a control method thereof are provided. The method includes: providing a control signal to an oscillating reflective mirror of the device; setting a frequency of the control signal gradually decreased from a maximal-setting-value of a resonant frequency of the mirror; judging whether a light detector receives a laser light reflected by the mirror according to an edge signal of the detector; judging whether a pulse width of the edge signal is equal to a predetermined pulse width when the detector receives the laser light: (1) increasing the frequency of the control signal when the pulse width of the edge signal is greater than the predetermined pulse width, (2) decreasing the frequency of the control signal when the pulse width of the edge signal is less than the predetermined pulse width. The time and labor for measuring the scanning frequency of the mirror may be saved.
摘要翻译：提供了一种激光扫描装置及其控制方法。该方法包括：向设备的振荡反射镜提供控制信号; 将所述控制信号的频率从所述反射镜的共振频率的最大设定值逐渐减小; 判断光检测器是否根据检测器的边缘信号接收由反射镜反射的激光; 当检测器接收到激光时，判断边缘信号的脉冲宽度是否等于预定脉冲宽度：（1）当边缘信号的脉冲宽度大于预定脉冲宽度时增加控制信号的频率，（2）当边缘信号的脉冲宽度小于预定脉冲宽度时，降低控制信号的频率。可以节省测量镜子扫描频率的时间和人力。
