Fringes are formed when the optical difference (OPD) between a reference wave front and a test wave front based on the interference of light is an integral multiple of the illuminating wavelength.

测试中，当测试波前相对于参考波前的光程差是照明波长的整数倍时形成干涉条纹，由此而形成的二维图就是干涉图像。

The cost of the optical system with the unitary wave front correctors instead of the adaptive wave front correctors is reduced significantly.

采用整体式波前校正器替代自适应式波前校正器可以大大降低光学系统的成本。

The algorithm calculated the wave front slope by a reusing core module manner and complemented the wave front reconstruction with the decomposition of matrix-vector multiplication.

该算法基于重复利用核心模块的方式完成波前斜率计算，利用矩阵与向量相乘的可分解性完成波前复原计算。
