Abstract
A simple method to objectively and simultaneously measure eye's longitudinal and transverse chromatic aberrations was proposed. A dual-wavelength wavefront measurement system using two Hartmann–Shack wavefront sensors was developed. The wavefronts of the red (639.1 nm) and near-infrared (786.0 nm) lights were measured simultaneously for different positions in the model eye. The chromatic wavefronts were converted into Zernike polynomials. The Zernike tilt coe±cient (first term) was used to calculate the transverse chromatic aberration along the x-direction, while the Zernike defocus coe±cient (fourth term) was used to calculate the longitudinal chromatic aberration. The measurement and simulation data were consistent.
