| 摘 要： | 采用共光路径向剪切干涉法测量三维温度场,通过两块波带板将待测波面分离成放大或缩小倍数不同的两波面进行径向重叠,在叠加区域实现剪切干涉。利用光学层析技术重建三维温度场,由于数据的非完全性,通常采用的代数迭代算法不能很好地解决重建精度这一问题。为此在算法中引入了

| Abstract: | The common optical path radial shearing interferometry is adopted to measure 3-D temperature field,the tested wavefront is divided into two wavefronts that have different amplificatory or contractible multiple by two zone plates,the two wavefronts make radial shearing interference in their overlap area.The 3-D temperature field was reconstructed by optical computerized tomography(OCT),the algebra is usually used cannot solve the problem of reconstruction precision very well for incomplete data in the proces... |
