Zusammenfassung:An optical sensor system with two or more optical sensors; two or more receivers; and an optical de-multiplexing system. Each optical sensor includes a fibre grating with a different wavelength characteristic. Each receiver includes a slope filter and a light detector and is associated with a respective one of the optical sensors. The optical de-multiplexing system is arranged to route light from each of the optical sensors to its associated receiver based on a wavelength of the light. Each slope filter is tuned to the wavelength characteristic of a respective one of the optical sensors and the slope filters are tuned to different wavelength characteristics
