摘　　要：在介绍红外触摸屏硬件的基础上,总结了红外触摸屏的三种扫描方式,重点对倾斜扫描算法进行了分析和研究,给出了倾斜扫描算法的模型。通过数学工具MATLAB对模型进行仿真验证,证明了倾斜扫描算法能够降低元件的密度,消除正交诡点,并且不延长扫描的时间,不但保证了红外触摸屏的性能,而且还降低了红外触摸屏的成本。On the basis of the infrared touch screen hardware, this paper summarizes the infrared touch screen three scanning methods, focuses on the tilt scanning algorithm analysis and research, and give the tilt scanning algorithm model. Through mathematical tools MATLAB simulation of the model, tilt scanning algorithm that can reduce the density of the element, to eliminate orthogonal sly points, and not to extend the scan time, not only to ensure the performance of the infrared touch screen, but also reduces the cost of the infrared touch screen.
