DESCRIPTION:Zeev Zalevski\nThe EPFL Photonics Chapter (EPC) is glad to p
 resent its next distinguished seminar in the frame of "SPIE Visiting
  Lecturer" program:\n\nSuper resolved and focal depth extended ophthalmol
 ogy\nProf. Zeev Zalevski\nBar-Ilan University\, Ramat-Gan​ (Israel)\n\
 nThe seminar is open to all students and faculty members\, and will be fo
 llowed by coffee and snacks.\nThe EPFL Photonics Chapter\n\n*** For orga
 nizational purpose\, please register via this form ***\n\n\nAbstract:\nD
 igital imaging systems as well as human vision system have limited capabil
 ity for separation of spatial features. Therefore\, the imaging resolution
  is limited. The reasons to this limitation are related to the effect of d
 iffraction i.e. the finite dimensions of the imaging optics\, the geometry
  of the sensing array and its sensitivity as well as the axial position of
  the object itself which may be out of focus. In this talk I will present 
 novel photonic approaches and means to exceed the above mentioned limitati
 ons and eventually to allow having super resolved imaging systems.\nThen\,
  novel all optical extended depth of focus concept based on “interferenc
 e” effect will be demonstrated for ophthalmic usage and implemented on c
 onventional refractive devices\, such as spectacles\, contact lenses and i
 ntraocular lenses. This extended depth of focus technology is capable of s
 imultaneously correcting various refractive errors\, such as myopia\, hype
 ropia\, presbyopia\, regular/irregular astigmatism\, as well as their comb
 inations.\nIn the last part of the talk a special device mounted on specta
 cles that allows translation of visual information into spatial tactile st
 imulation of the cornea\, will be discussed. This device can lead blind pe
 ople to “see” by providing a novel and a non-invasive sensory substitu
 tion allowing blind people to perceive images after teaching them to assoc
 iate the tactile spatial feeling of the stimulation of their cornea to rea
 l spatial shapes and images.
