本文的方法不需要产生非球面参考波前，这就避免了通常干涉方法测量非球面的特殊困难。

This method needs no aspheric reference wavefront which is required in the conventional interferometric aspheric measurements and is extremely difficult to be produced.

在高功率固体激光驱动器中，参考波前标定是自适应光学系统应用过程中的关键技术之一。

In high power solid-state laser driver, the calibration of reference wavefront is a key technique in the use of adaptive optics system.

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。

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.
