Compact snapshot hyperspectral camera for ophthalmology
(2024) In Optics Continuum 3(4). p.565-573- Abstract
Hyperspectral imaging is an emerging technique that allows measurement of spectral absorption at each point of a scene, thus offering the capability to identify and characterize important biomarkers 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, and to the best of our knowledge, we present a novel concept of a 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... (More)

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.
