Distributed optical fiber sensor systems are prospective candidates for the environmental pollution monitoring over large industrial sites. Among particular optical probes that are attractive for this application are the refractometric ones. However, despite all previous work on this subject, the performance limit of these probes, especially in case of the micro-optical of fiber-optical design, is not yet established. To clarify this point, computer simulations dealing with the response of the novel paraboloidal-shaped micro-optical probe to small changes in the refractive index of the surrounding media are presented. The relative sensitivity concept, which is the ratio of the probe output in two different media, is introduced. The relative sensitivity is proposed as an objective basis for the comparison of refractometric probes.
