| 摘 要： | 讨论了非线性对正弦相位调制Fabry-Perot(F-P)干涉术的影响.当用分块积分讨论相调F-P干涉术的输出光强,并作近似处理时,就可以给出类似的结果,所以把这种方法进一步推广到对相调F-P干涉术的研究中.同时提出了两种测量压电陶瓷非线性系数的方法,在实际测量得到的非线性系数基础上,完成`影响大小的数值计算和实验研究.最后证明提出,相调F-P干涉术的初相位应选择在π/4附近以及它可用于测量精细表面的粗糙度或其轮廓.

| Abstract: | The nonlinear piezoelectric effect of piezoelectric ceramics on the sinusoidal phase modulation Fabry-Perot(F-P) interferometry was mainly discussed besides an introduction of the analysis of this effect on the block integral phase modulation interferometer.When discussing the output light of the phase modulation F-P interferometry in paragraphs and adopting a suitable approximating,a similar conclusion was drawn.So this method could be further extended into the study of the phase modulation F-P interferome... |
