Design, Fabrication, Testing of an Optical Sensor to Measure Effective Retinal Cone Illuminance In Situ
thesis
posted on 2018-11-27, 00:00 authored by Giacomo D'AlessandroThis thesis has achieved the realization of the first sensor to measure effective retinal illuminance for cones in absolute units, approximating the acceptance angle of a cone photoreceptor cell, if positioned such that its axis is aligned in the anatomically correct orientation for cones at the locus of the measurement within the retina. The sensor designed is different from all the ones already found in literature because it approximates the optical properties of a cone photoreceptor cell. Till now, measurements obtained in literature have been referred only in relative values and we have provided a good measuring approach to obtain values in absolute units. A first test of the sensor has been done on sheep eyes that were the only ones available for the strict times and constraints of this work. The results have shown that retinal illuminance decreases more and more from the center of the retina (0 degrees) to different angles (30 – 45 degrees). The results have also shown that different eyes have similar measurements between them.
