【摘要】 基于在三维形貌测量中广泛使用的傅里叶变换轮廓法,提出了一种测量KTN晶体二次电光系数的新的方法,并设计了基于麦克尔逊干涉的实验平台,进行了多次试验,得到了KTN晶体二次电光系数张量矩阵三个独立分量中的确定值.更多还原

【Abstract】 We proposed a new method to measure Quadratic electro-optic coefficient in KTN crystal based on Fourier transform profilometry method widely used in 3D topography measurement.We designed an experiment platform based on Michelson interferometer,one of the three independent components ——h₁₁ in KTN crystal quadratic electro-optic coefficient tensor matrix was calculated.更多还原
