Multi-Spectral and Single-Shot Wavefront Detection Technique Based on Neural Networks

Photonics
Conventional wavefront sensors face challenges when detecting frequency-domain information. In this study, we developed a high-precision, and fast multi-spectral wavefront detection technique based on neural networks.

Wavefront-Guided and Wavefront-Optimised Laser Treatments

Türk Oftalmoloji Dergisi, 2012
Optical aberrations of the eye are the errors of the optical system that limit the resolution, contrast and amount of detail in the image formed on the retina. Wavefront technology allows us to measure these optical aberrations, calculate mathematically, and transfer this information into excimer laser system to perform customized treatment on the ...

Wavefront Control

, 2017
My research work falls under the theme of "High Angular Resolution", defined as the study and development of methods and instruments for approaching the limit of diffraction, in spite of dynamic aberrations. They focus on the measurement of the wavefront for adaptive optics and active optics and on the effects of optical propagation in the lower ...
