Abstract[English]
An optical sensor system includes a light source and an optical fiber configured to transmit wavelengths of light received from the light source. A Bragg grating is disposed in the optical fiber. The Bragg grating is configured to reflect a wavelength of the wavelengths of light based on a force applied to the optical fiber that corresponds to an intraocular pressure (IOP). An optical spectrum analyzer is configured to detect the wavelength.[French]

Un réseau de Bragg est disposé dans la fibre optique. Le réseau de Bragg est conçu pour réfléchir une longueur d'onde des longueurs d'onde de lumière sur la base d'une force appliquée à la fibre optique qui correspond à une pression intraoculaire (IOP). Un analyseur de spectre optique est conçu pour détecter la longueur d'onde.
