摘　　要：将CCD引入放大率法焦距测量系统中，把CCD当作一把精度很高的"尺子"取代读数显微镜进行"读数"，形成透镜焦距的CCD图像测量系统，使焦距测量的光电自动化成为可能。An image measurement system of lens focal length, based on magnification method, with CCD camera is introduced. in which the photosensitive area of the CCD is used as a ruler with high accuracy instead of reading microscope. The system makes it possible the photoelectronic automatical measurement of the focal length. The measued results of two lens is given.
