摘要

The method involves determining characteristics of an imaging device and computing wave front aberration of a lens of the device from the characteristics based on a mathematical model. The aberration is indicated as a basis function weighted by Zernike coefficients. The model includes a free parameter that is optimized when a value of the function exceeds its upper limit. The model with optimized values is used for designing the lens. The free parameter includes refractive index of a lens of the device, thickness of the lens in the middle and radii of curvature of the lens. An independent claim is also included for an optical imaging device.
