A novel concept of compact, snapshot hyperspectral camera for ophthalmology.

Hyperspectral imaging is an emerging technique that allows to measure the spectral absorption at each point of a scene, thus offering capability to identify and characterize biomarkers important for clinical practice and therapeutic research as well as enhancing image identification of important structures. So far, few hyperspectral cameras have been used for retinal scanning because of the need to acquire the image in a fraction of a second. Here we present a novel concept of snapshot hyperspectral camera suited for retinal imaging. We demonstrate the technique by presenting the optical density spectrum of a healthy patient’s retina in the 450-700 nm range, together with the spectral response of several retinal features.
