研制了一种新型光纤—波导精密对准仪，并对其进行了精度计算与分析仪器主要根据端面耦合原理设计，有平动与转劝分离式结构及微机闭环控制电路系统，分辨率较高．

his paper describes a new fiber optical waveguide precision alignment instrument. Its precision is calculated and analyzed. This instrument is designed mainly on the basisof endallfire coupling principle. The system is of advanced separated structure for parallel changeof place and rotation. The instrument has a piezoelectric material driver and an electric circuitsystem of the loop locked control by a micro-computer.
