Optical Aberrations and Wavefront
Türk Oftalmoloji Dergisi, 2014 The deviation of light to create normal retinal image in the optical system is called aberration. Aberrations are divided two subgroup: low-order aberrations (defocus: spherical and cylindrical refractive errors) and high-order aberrations (coma ...
