Higher-Order Aberrations Correction and Vision Analysis System for Human Eye
Besides defocus and astigmatism that can be corrected by wearing spectacles or contact lens, there are also higher-order aberrations in human eye which influence the visual function. By using adaptive optics technology, the system of higher-order aberrations correction and vision analysis for human eye has been developed. The principle of correcting high-order aberrations and vision analysis is presented, and key element technologies, such as wave-front corrector, Hartmann wave-front detector and control system, are explained, correct capability to Zernike modal aberrations are listed, most of aberrations that RMS error equals 0.5λ decreased below 0.2λ, the simulated result is shown to explain how the function of system is realized. It is an effective tool to study the influence of higher-order aberrations to vision function.
