水中湍流是影响水下光学系统性能的重要的潜在因素。用波前检测的方法对水中湍流对激光束传输的影响进行实验研究，测量了实验条件下水中湍流产生的波前畸变的大小，对波前畸变进行了Zernike分析，还对波前补偿自适应系统在水下成像的应用进行了探索。结果表明：水中湍流引起的激光束波前的起伏降低了图像的分辨率，自适应光学系统在其校正范围内能有效地校正畸变，提高图像质量。
Abstract
Underwater-turbulence may have an impact on the performance of underwater imaging system. The impact of underwater-turbulence on laser beam propagation is studied with wave-front test. The distortion introduced by underwater-turbulence is measured and analyzed using the Zernike polynomial. The adaptive optical system with wave-front compensation is investigated for underwater imaging. The result shows that underwater-turbulence reduces the resolution of underwater imaging system. Calibration experiment is carried out to show that adaptive optical system can improve the quality of underwater images effectively.
