Paper Abstract

The construction and principle of operation of optical fibre refractometer is given in the paper. The refractometer operates on attenuation changing measurement. The attenuation changing is a function of mode radiation from specially bent optical fibre. A quartz step index, optical fibre with polymer coat and 130 um core in diameter was used to develop the model of the sensor. At the place of bending the coat was removed. The sensors with a different diameter of bending were examined in liquids with known refractive indexes. In the transmitter was used LED while receiver was made with pin fotodiode.
