Paper Abstract

Advanced fiber-optical displacement sensors are being developed. We propose to use a reflection fiber-optical sensor of new configuration- two pairs of fibers creating the defined angle between the tips of fibers to indicate and measure angular and linear displacement. The latter can e also used as refractometer to provide drastic improvement of measurement sensitivity in comparison with the recently developed three-fiber measurement method. We describe the design of the measurement set-up and signal processing electronics. Results of computer simulation and experimental investigation are presented. Attained sensitivity of the displacement sensor 1702 mV/micrometers . Obtained refractometer sensitivity 2(DOT)10-6RIU.
