Multispectral Analysis for Fundus Imaging: Effects of Light Source Spectral Distributions

Abstract

In this research we conducted multispectral analysis for fundus imaging, which enabled us to simulate how fundus chromaticities change depending on the spectral distributions of the illumination light source. Our results show that the spectral distributions of the light directly affect fundus chromaticities. The longer the wavelength component in the light source, the more the fundus chromaticities shift toward yellow. Our results suggest that multispectral information is useful in finding the best light source spectral distribution for imaging the fundus, which could enable easy detection of abnormal parts of the fundus.
