Abstract:Precise real-time observation of retinal features, ophthalmic biometric identification and the prescription of aberration-specific contact lenses demand detection and eventual correction of ophthalmic aberrations at rates higher than those of microfluctuations and involuntary movements inherent to the eye. Detection and correction can be accomplished in a closed-loop adaptive optical system containing a wavefront sensor and an adaptive corrector.
 
This article presents recent advances in both application-specific sensor design and performance, and in neural-network solutions to the control of an adaptive optical system for the detection of ophthalmic aberrations. The match between custom simulation and experimental results are reported. The results indicate the potential of components that are compatible with standard silicon technology to the medical scenario.
