Based on the principle of coarse grating displacement measurement system made of MOS sensor, the relationships between track velocities and accuracy of the system are analyzed theoretically.
Using an industry standard Size 15 modular mounting pattern, the index mark on the disc hub can be coarse aligned to the index sensor position on the housing.
使用业界标准尺寸15模块化安装模式，光盘上的枢纽指数标记可以粗对齐房屋价格指数上的传感器的位置。
