| 摘 要： | 本文介绍了检测织物密度的原理与仪器结构。将织物放在聚光系统中，织物的像通过空间滤波器转变成对比度较高的明暗相间的直条纹，并成像到ＣＣＤ上。ＣＣＤ将条纹的明暗信号转换成电信号，经过放大、滤波、微分电路处理，再送入到单片机系统中做数据处理。该测试装置具有测试速度快、自动化程度高和非接触测量等优点，能够实现织物密度的在线检测，测试精度达到△Ｎ＜１。

| Abstract: | The paper present principle of detection of fabric density and instrument structure. The fabric was putted in illumination system. The fabric image was converted to high constrast fringes through space filter. The fringes was imaged on CCD and was converted to electrical signal. After been amplifying, filtering and plastricing, the signal is acquired and processed by microcomputer. This apparatus is provided with high measuring speed and detecting fabric density on line, measuring accuraty △N<1. |
