摘要:
结合Mach−Zehnder干涉技术得到干涉条纹图，详细介绍如何运用干涉数据评估算法(IDEA)软件实现掩膜、二维快速傅里叶变换和相位去包裹等过程，从而获得干涉条纹图对应的相移分布图. 结果表明，基于IDEA软件的干涉图的相移获取只需通过简单的菜单命令即可完成，并可以有效降低噪声、阴影对测量结果的影响. 因此，使用IDEA软件实现干涉图的相位获取对光学干涉测量研究领域具有一定的意义.
Abstract:Using the interferograms obtained by Mach-Zehnder interferometry, it was introduced how to use Interferometrical data evaluation algorithms (IDEA) software to realize processes of Mask, 2D Fast Fourier Transformation and Phase Unwrapping, thus phase shift distribution diagrams corresponding from the interferograms were obtained. The results show that the phase shift of the interferograms can be extracted by simple menu commands in IDEA. Meanwhile the optical noise and shadows in the interferograms can be effectively reduced. Therefore, the phase extraction based on IDEA has certain significance in the application of optical interferometry.
