Paper Abstract

Measurement of oxygen saturation has proved to give important information about the eye health and the onset of eye pathologies such as Diabetic Retinopathy. Recently, we have presented a multi-aperture system enabling snapshot acquisition of human fundus images at six different wavelengths. In our setup a commercial fundus ophthalmoscope was interfaced with the multi-aperture system to acquire spectroscopic sensitive images of the retina vessel, thus enabling assessment of the oxygen saturation in the retina. Snapshot spectroscopic acquisition is meant to minimize the effects of eye movements. Higher measurement accuracy can be achieved by increasing the number of wavelengths at which the fundus images are taken. In this study we present an improvement of our setup by introducing an other multi-aperture camera that enables us to take snapshot images of the fundus at nine different wavelengths. Careful consideration is taken to improve image transfer by measuring the optical properties of the fundus camera used in the setup and modeling the optical train in Zemax.
