摘要
对延迟捕获的基本原理进行了系统的分析，详细介绍了利用延迟捕获功能实现计时计数法测量转速的具体方法和实例。此方法已应用在粘度测试仪器中切变率指标的测量上，经实际使用表明具有软硬件结构简单、成本低、精度较高、运行可靠等优点，对于一些在嵌入式应用中需要测量转速指标时，可谓一种良好的方法。
The basic principle of delayed capture has been systematiically analyzed. The method and actual case of measuring rotation speed with delayed capture have been introduced in detail. This method has been used in blood viscosity measure apparatus for shear rate measurement. The application of it shows various advantages like simple software and hardware structurement, low cost, high precision and reliability. It is a good method for the embedded application to measure rotation speed.
