All of the existing holographic wavefront sensors are either bulky or have low accuracy of measuring wavefront aberrations. In this paper, we present an improvement of the holographic method of measuring wavefront aberrations using computer-generated Fourier holograms. The novelty of this work lies in the proposed approach to the synthesis of Fourier holograms, which are implemented using phase-only SLM. The main advantages of this method are the increased diffraction efficiency compared to the previously known methods, and the more compact implementation scheme due to the elimination of the conventional Fourier-lens. The efficiency of the proposed method was confirmed by numerical simulation and optical experiments.
现有的所有全息波前传感器要么体积庞大，要么测量波前像差的精度较低。在本文中，我们提出了一种使用计算机生成的傅里叶全息图来改进测量波前像差的全息方法。这项工作的新颖之处在于所提出的傅里叶全息图合成方法，该方法使用纯相位空间光调制器来实现。与先前已知的方法相比，该方法的主要优点是衍射效率提高，并且由于省去了传统的傅里叶透镜，实施方案更加紧凑。数值模拟和光学实验证实了所提方法的有效性。
