光具座

该方法克服了在光具座上进行实验时的调节难度大、不易测量和测量误差大等问题。

The difficulties of adjusting and measuring and the large system errors on the optical bench are eliminated by the method .

在原来光具座测量透镜焦距的装置基础上，用CCD代替人眼作接收器时，正确判定焦面是实验的关键。

Linear CCD is used as receiver on behalf of eyes on the basis of originally experimental equipment measuring the focal length of lens .

为实现透镜焦距的自动测量，在原来光具座测量透镜焦距的基础上，用线阵CCD代替人眼作为接收器，开发一自动检焦系统。

In order to measure the focal length of lens automatically , linear CCD is used as receiver on behalf of eyes on the basis of original experiment equipment measuring the focal length of lens .
