Abstract

An optical system for sensing an environmental parameter, comprising: an optical pulse generator for generating an excitation pulse; a pulse splitter for splitting the excitation pulse into a sensing pulse and a reference pulse; a sensing arm for receiving the sensing pulse, the sensing arm comprising an emission sensor for sensing the environmental parameter, the optical emission sensor generating a first measurement pulse having a measurement wavelength; a reference arm for receiving the reference pulse, the reference arm comprising an emission artifact adapted to convert the reference pulse into a second measurement pulse having the measurement wavelength; a time delay line for delaying a relative propagation of the measurement pulses; a light detector for measuring an optical energy of the first and second measurement pulses; and an optical link for optically connecting the pulse generator to the pulse splitter, and the sensing and reference arms to the light detector.
