摘要
在Gullstrand LeGrand眼模型的基础上 ,构造不同的眼光学模型 ,分别研究了角膜非球面、晶状体非球面和昌状体折射率在眼光学成象中的作用 通过比较各模型系统的Zernike标准多项式系数 ,分析了非球面和梯度折射率对眼光光系统各象差的影响
Several different eye models are constructed based on the eye model of Gullstrand-Le Grand.The actions of aspheric surfaces of cornea and lens,and the action of gradient-index of the lens on optical image of the eye are investigated respectively.By comparing the coefficients of Zernike standard polynomials,the effects of aspheric surfaces and gradient-index on aberrations of the eye optical system are analyzed.In addition,the performances of modulation transfer functions of different eye models are studied also.
