为了顺应学科发展趋势和满足巢丝现场工业测量要求，针对现有生丝（纤维）细度测量仪器和检测方法存在的问题，提出一种基于线阵CCD非接触式实时动态检测生丝细度的设计方案。旨在研发一种具有高精度、准确率高、非接触性、动态检测、便于计算机处理、易于和自动控制设备连接的生丝细度的光电测量仪。本文对激光光源理论设计、光学系统的设计、CCD图像传感成像模式的选取、视频信号处理方法实验与研究，从理论设计到各个功能模块的参数设定，提高了系统测量精度。系统解决了光源照度不稳定性和生丝透明度造成的影响，避免了CCD在亮背景成像时易饱和、及生丝样品抖动引起的失真,最终通过实验验证，研究方案有一定的可行性和实用性。

Real-time dynamic measurement of raw silk fineness

To conform the academic development trend and meet measurement requirements of raw silk fineness at silk nest site. There are some problems in existing raw silk (fiber) fineness measuring instruments and detection methods. A sort of design scheme contain contactless, real-time and dynamic raw silk diameter measurement based on linear CCD array. The goal is to develop a high precision, high accuracy, non-contact, motion detection, ease of computer processing, easy and automatic control equipment connected to the fineness of raw silk photoelectric measuring instrument. This article presents theoretical design of the laser light source, optical system design, CCD image sensor imaging mode selection, the video signal processing experiment and method.secondly the paper proposes the study on how to improve the measuring accuracy of the measuring system from the theory and the various modules of the design parameters. It solve effection in instability of the light illumination and raw silk transparency of raw silk, to avoid CCD saturation due to bright background and the distortion caused by raw silk jitter.Finally, the design is proved in feasibility and practicality through experimental results.
