阵列波导光栅薄膜的制备及性能。

Grating spectrometer is used to carry on the detection of laser-induced plasma of al and sio2 sample .

本文利用光栅光谱仪对铝样品和二氧化硅样品的激光诱导等离子体光谱进行了探测。

Only one piece grating was used in absolute coding method , specified regular code was arranged on the grating , each angle was given a unique and corresponding code , even though restarting the instrument after power cut off , this correspondence remains unchanged , which ensures the reliability of angle measurement .

绝对编码法在一片光栅上刻以特定规则的编码，被测量的所有角度信息均有唯一编码与之对应，断电后重新上电这种对应关系不变，从而保证了数据的可靠性。
