    • A wavefront aberration measuring apparatus and method are provided to precisely measure the wavefront aberration with the single measurement by measuring the wavefront aberration of the laser beam through at least two interference fringes. A wavefront aberration measuring apparatus includes an interferometer dividing the laser beam to generate at least n interference fringes(n is natural number more than 2), and a wavefront aberration interpretation part determining the size and direction of the wavefront aberration of the laser beam at the same time by using the n interference fringes.
    • 提供了一种波前像差测量装置和方法,用于通过至少两个干涉条纹测量激光束的波前像差,通过单次测量来精确地测量波前像差。 波前像差测量装置包括:干涉仪,其分割激光束以产生至少n个干涉条纹(n是大于2的自然数);以及波前像差解释部分,确定激光束的波前像差的尺寸和方向 同时使用n个干涉条纹。
