Confocal laser scanning technology combined with swept-source optical coherence tomography (SS-OCT) uses lasers as the light source. Multi-wavelength confocal lasers scan the retina point by point to acquire fundus images at different depths and layers respectively, enabling more microscopic observation and pathological analysis of the retina at the cellular level. By observing changes in the animal fundus, it facilitates research in various disciplines such as clinical medicine, bioengineering, and life sciences.
