摘　　要：分析了位移型光衰减器的工作原理，利用波动理论导出了横向和轴向位移光衰减器的衰减公式和衰减曲线，所得到的理论曲线与实际制作参数完全吻合，并对位移型光衰减器的分类、使用及性能作了系统的阐述。In this paper,the operation principle of the displacement type optical attenuator is analyzed. The attenuate formulas and curves of the two kinds of optical attenuatores with cross and axial displacement are derived from wave theory. The theoretical curve corresponds with experimental curve. At last, the type, application and performance of the optical attenuator is described systematically.
