摘要
提出了一种以线阵CCD传感器取代读数显微镜，以8253可编程芯片实现自动测量并实时显示测量结果的相机镜头焦距测量系统；论述了系统的工作原理和软硬件的实现，分析了系统的测量误差；证明了系统的可行性和先进性，系统具有较高的实用价值和应用前景。
An auto-measuring system of camera lens is advanced. This system uses linear CCD sensor as the detectorinstead of reading microscope, and realizes auto-measuring and displaying results using 8253 CMOS chip. The principleand the realization of the hardware and software are discussed. The measuring error of the system is analyzed. The feasi-bility and progress of system is argued. The system has upper practical value and application prospect.
