Development of a fundus camera with adaptive optics using a pyramid wavefront sensor
(2012-03-02)This PhD thesis presents the building of an adaptive-optics system based on a pyramid wavefront sensor applied to the imaging of the human retina (fundus) in vivo. The instrument aims to simultaneaously measure the ocular ... -
Shack-Hartmann Wavefront Sensing of Optical Vortices in a Turbulent Field
(2011-07-18)An optical vortex is a point on an optical wavefront where there is a null of intensity and the phase is undefined. When the phase is defined over the range 2 pi radians, as is commonly done, the phase surrounding the ...
