为提高波前传感器的波前探测速率，研究了基于全息术的无计算波前传感新方法。在薄全息图近似下，推导出基于快速傅里叶变换(FFT)算法的数值模型，并数值模拟了全息波前传感器对低8阶Zernike项像差的探测过程。结果表明，波前探测误差均方根值（RMS）为0.24 rad。搭建实验平台对数值模拟的结果进行了验证，波前探测误差RMS值达到0.29 rad。实验结果表明，基于全息术的无计算波前传感方法可以高效探测低阶Zernike像差。

To increase wavefront detecting speed of the wavefront sensor, a new computing-free method based on holography is researched. With thin hologram approximation, we get the numerical model based on the fast Fourier transform (FFT) algorithm and the first 8 order Zernike aberrations are detected by holographic wavefront sensor under this numerical model. The root-mean-square (RMS) value of detection error is 0.24 rad. An experimental device is set up to validate the numerical simulation in our laboratory and the RMS value of detection error is 0.29 rad. The experimental results indicate that the computing-free wavefront sensing method based on holography can detect the low order Zernike aberrations with high efficiency.
