The coarse grating linear displacement measuring Sensor has many advantages. But only with a numerical control converter, it can be interfaced with current NC machine tools.
粗光栅线位移传感器有很多优点，必须加上数控转换器后，才能与流行的数控系统接口。

The CCD detector was used to take place of the photomultiplier which was widely used as the optical-electrical converter, and the fast analysis of the spectrum was realized by incorporating a grating.
