对"Needle"法提出了一种更直观,物理上更容易理解的推导方式,对其中的相关问题作出了详细推导,并基于此设计出了在激光陀螺研制过程中遇到的非偏振大角度高精度减反膜.

A new model of the "Needle" method that is more intuitionistic and physically more easily interpreted has been brought out, and the corresponding subject has been deduced particularly. The needed large incidence angle, high accuracy, non polarization anti reflection coating encountered in the process of development of laser gero has been designed successfully.
