Design and Realization of High Precise Time Interval Measure System Based on FPGA

文中利用逻辑门延迟线法,设计了一个集成在FPGA内部的高精度时间间隔测量的模块。该设计可以实现对时间间隔的高精度测量,并采用激光测距法对测量结果进行检验。该方法具有简单灵活、体积小等优点,可用于高精度激光测距、无源高精度定位等应用场合。

The lecture uses the method of logic gate delay line to design a module of high precise time interval measuring, which is integrated on a single FPGA. The design can implement high precise time interval measuring and use the method of laser measuring distance to check the result. The design has the advantages of simplexes, agility and small bulk, etc. It can be used in many application situations, such as high precise laser measuring distance, passive high precise orientation etc.
