Abstract: An optical system for sensing an environmental parameter, comprising: a pulse generator for generating a first pulse having a first wavelength and a second pulse having a second wavelength; a pulse splitter for splitting each one of the first and second pulse into a sensing pulse and a reference pulse; a sensing arm for receiving the sensing pulses therefrom and comprising a spectro-ratiometric sensor; a reference arm for receiving the reference pulses; a time delay line for delaying a relative propagation of the sensing pulses and the reference pulses; a light detector for measuring an optical energy of the sensing pulse and the reference pulse, for the first and second wavelengths; and at least one optical link for optically connecting the pulse generator to the pulse splitter, and the sensing and reference arms to the light detector.
