Resumen

We present and evaluate a way to utilize vortex phase masks to decimate the costs of current methods for retinal cone counting. This new way of tackling the accuracy in cone counting, should also allow us to incorporate the new to current algorithms, making them faster and with an accuracy beyond the Rayleigh Criterion, according with previous research on the subject.

Motivation The cone counting systems widely used today are highly limited by the exorbitant costs of AO hardware (i.e. the RTX-1, Imagine Eyes, Orsay, France). A new detection method based on a phase mask vortex would entail a great cost reduction for the medical industry and a more accurate numbering of cones in the retina (Kawano Feng et al.). Applying a new coronagraph inspired method should make current systems faster and with an accuracy beyond the Rayleigh Criterion. This method has been successfully implemented in an astronomical setting of exoplanet exploration (Tamburini et al., "Overcoming the Rayleigh criterion limit with optical vortices" Tong and Korotkova).

Palabras clave: visual, optics, eye, cone, cells, photoreceptor, retina, coronagraph, counting, mosaic.
