Abstract
The multi-aperture system of the present invention provides a retinal oximetry apparatus for determining the level of oxygen saturation in retinal vessels using a lenslet array comprising at least seven lenses for the simultaneous measurement of reflected light with at least three wavelengths and at least four polarization states. The multi-aperture system of the present invention further provides an apparatus for determining the level of oxygen saturation in retinal vessels using a lenslet array comprising at least ten lenses for the simultaneous measurement of reflected light with at least three wavelengths for oxygen measurement, at least three wavelengths for melanin content, and at least four polarization states. Methods of operating the same are also provided.
