Abstract
A spectroreflectometric system for performing a spectral analysis on the fundus of a patient's eye is provided. The system projects probing light towards the fundus of the eye and collects return light representative of an image of the fundus. An interface module positioned at a sensing interface at an image plane of the fundus is provided and includes an optical fiber light collector having a collector input extending along the sensing interface for collecting the return light, and a collector output connectable to an imaging device. The interface module further includes at least one extraction optical fiber having a fiber input extending at the sensing interface and a fiber output connectable to a spectral analyser. The fiber input is integrated into the collector input so as to collect a portion of the return light corresponding to an analysis area within the image of the fundus.
