A Hartmann-Shack wave-front sensor is used to measure the wave aberrations of the human eye by sensing the wave front emerging from the eye produced by the retinal reflection of a focused light spot on the fovea. Since the test involves the measurements of the local slopes of the wave front, the actual wave front is reconstructed by the use of wave-front estimation with Zernike polynomials. From the estimated Zernike coefficients of the tested wave front the aberrations of the eye are evaluated. It is shown that with this method, using a Hartmann-Shack wave-front sensor, one can obtain a fast, precise, and objective measurement of the aberrations of the eye.
哈特曼-夏克波前传感器通过检测由聚焦在中央凹上的光斑的视网膜反射所产生的、从眼睛出射的波前，来测量人眼的波像差。由于该测试涉及波前局部斜率的测量，因此通过使用泽尼克多项式进行波前估计来重建实际波前。根据测试波前的估计泽尼克系数来评估眼睛的像差。结果表明，使用这种方法，借助哈特曼-夏克波前传感器，可以快速、精确且客观地测量眼睛的像差。
