    • 科技新闻播报:在点衍射干涉测量领域,一项创新的相位解包方法引起了广泛关注。该方法基于空洞空间卷积,将自编码器结构与空洞空间卷积相结合,实现了对包裹相位图像的高精度、高效以及抗干扰检测。研究团队制作了大量多样化的数据集,用于训练和优化这一算法,使其能够准确识别包裹相位所在阶次,并快速处理得到高精度的解包结果。与传统的解包算法相比,该方法在时间和精度上都展现出了显著的优势。处理一幅图像的平均时间仅需0.035秒,远低于传统方法的1秒以上。同时,实验结果表明,该方法的解包结果与专业干涉图像处理软件的枝切法处理结果相近,均方根误差值为0.022 2 rad,面形拟合结果的峰谷差值仅为0.012 1λ,均方根差值也仅为0.004 2λ。这一突破性的研究为点衍射干涉图像处理的高精度相位解包提供了新的可行方案,有望在相关领域发挥重要作用。
