Electro-optical device, an apparatus comprising the electro-optical device and a method of conducting functional near-infrared spectroscopy analysis using such an apparatus

Abstract

An electro-optical device, an apparatus comprising the electro-optical device and a method of conducting functional near-infrared spectroscopy analysis using such an apparatus. The electro-optical device comprises: a light source arranged to irradiate a target spot of the head of a subject with light emission including a plurality of light components having distinct wavelengths, wherein light components with distinct wavelength are arranged to be partially absorbed by hemoglobin in blood passing though the target spot with distinct absorption ratios; and a light sensor arranged to detect light reflection from the target spot, wherein light reflection is adapted to be further processed for determination of relative concentrations of oxygenated hemoglobin and deoxygenated hemoglobin in the target spot based on a change of each of the light components with respective wavelength in the light reflection when compared to the light emission.
