摘要
本文结合实验测量给出了光纤输出光强高斯分布的具体表达式I_((?)z)=[A_0/(1+kz)~2]·exp[-2r^2/(1+kz)~2],并相应建立了光纤束反射收集光强灵敏度曲线I_(反(z))-Z 的最佳计算模式,理论计算与实测的I_(反(z))-Z 相一致。在此基础上制作了静水压及声压传感器,其实验结果与计算相符合,再次表明光纤束设计理论的普遍适用性。
On the basis of experimental measurement,the outputlight intensity of a fiber optic is Gaussian distribution:I(r,z)=[A_0/(1+kz)~2]exp[-2r^2/(1+kz)~2]:accordingly,a appropriate way to calculatethe sensitivity curve of reflected light power collected Ir(z)—z is set upfor fiber optic lever.The theoretical calculated Ir(z)—z curve is sameas the experimented result.Both a pressure sensor and a hydrophone havebeen designed,and the measured results are in agreement with calculated.It indicated that the design theory of fiber optic lever is universally app-licable.
