A purpose of this invention is allow sensors to be placed at locations as close to a region of interest as possible, i.e. a few tenths of a millimeter from a probe, the target material and each other. The invention allows the user to reproduce and actively follow these locations from a remote location and at a distance, connected with to the locations with an arbitrary length of single mode optical fiber cable, and perform the sensor functions in a controlled environment using the sensor of choice without affecting the experiment.
