Zernike mode reconstruction model of human eye wavefront aberrations based on Hartmann-Shack sensor is introduced. Three algorithms, including Gram-Schmidt orthogonal transformation, Householder transformation and singular value decomposition, are deduced and compared with each other. Through simulation by the experimental data, the results suggest that the accuracy of the three methods is equivalent and singular value decomposition is the relatively ideal algorithm of wave-front aberrations of human eyes.
