角度传感器编码光栅盘设计

对角度传感器中的动光栅进行了精心设计，综合了普通增量光栅和绝对光学码盘的优点，将辐射光栅、定位光栅，编码码道刻制在同一光学圆盘上，为实现测量的小型化，精密化，数字化，自动化和快速反应，提供了一种可供选择的新型测角方法

The Design of Angle Sensor Code Grating Tray

The angle sensor is widely used in precise measurment of angle. Its main part is thegrating gair. According to the advantage of common grating and absolute optical code.tray,the moving grating of angle sensor is designed meticulously. The radiation grating,locating grating and code tracks are carved on the same glass disk. Measuring the anglecompactly, ptecisely,numeritaly, automaticly and rapidly was achieved.
