【Abstract】 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.更多还原
