Abstract

We report a large field of view FOV low-cost smart fundus camera with non-mydriatic and spectral band illumination features for the purpose of diagnosing central nervous system diseases such as Alzheimer’s disease. By combining a customized optical lens group, ring light emitting diode light source, Li-battery, and Raspberry Pi we can port the spectrally selected light source through a 4 mm diameter pupil. Taking advantage of the open hardware platform and Linux operating system, we integrate two narrowband filters explicitly selected based on the unique spectrums of biomarkers (580 nm and 660 nm) with a Raspberry Pi camera module to obtain high quality images for the purpose of enhancing the visibility of retinal vasculature and nerve fiber layer.
