Abstract
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.
