This paper presents a laboratory study of the aberrations calculation in underwater turbulence using the Shack-Hartmann wavefront sensor. The wavefront decomposition method and Zernike polynomials determine the aberration parameters. In our experimental setup, the turbulent phase screen generator is located in two locations: near the transmitter and therefore far from the receiver, and near the receiver and consequently far from the transmitter. Additionally, we investigate the impact of aperture diameter on turbulence-induced aberrations in the optical receiver system. However, it is essential to note that the coefficients of Zernike polynomials obtained using this method are subject to errors caused by receiver sensor noise and correlation between the polynomials. To address this, we first calculate the coefficients in different arrangements and then correct measurement errors arising from sensor noise and polynomial coefficient correlation.
本文介绍了一项利用夏克-哈特曼波前传感器计算水下湍流像差的实验室研究。波前分解方法和泽尼克多项式用于确定像差参数。在我们的实验装置中，湍流相位屏发生器位于两个位置：靠近发射器，因此远离接收器；靠近接收器，因此远离发射器。此外，我们研究了孔径直径对光接收器系统中湍流诱导像差的影响。然而，必须注意的是，使用这种方法获得的泽尼克多项式系数会受到接收器传感器噪声以及多项式之间相关性所导致的误差影响。为了解决这个问题，我们首先在不同配置下计算系数，然后校正由传感器噪声和多项式系数相关性引起的测量误差。
