Welcome to the web-page
of the project Photonic analysis
of the retina’s biometric photoabsorption.

The goal of this project is to study the pupil’s response to light pulses of extremely low intensity, to investigate how this response relates to the underlying neural circuits, to design algorithms that effectively recover this information and to apply techniques for identification and medical purposes.

This project is co-financed by the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE, project identifier Τ1ΕΔΚ-04921.

Retina Photonics

The pupil light reflex is an “instinctive” constriction of the pupil’s diameter upon light illumination. Upon termination of the illumination, the pupil dilates again to its original diameter. The process is governed by neural circuits, which emanate from the retina, pass through a processing center in the mid-brain, and return to the pupil’s muscles.

Pupillometry measurements carry useful information about brain function, which in many cases has medically diagnostic value. Hence pupillometers can assess various opthalmic and neurological diseases.
