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 results indicate that the dispersivity of the shock arriving times and the obliquity of the shock wave front are obviously increased with increasing the radius of test.

结果表明，随着测试半径增大，爆轰到达时间分散性明显增加，爆轰波阵面的倾角也增大。
