摘要: A method is proposed to implement an optical fibre sensor for the measurement of refractive index liquids whose attenuation may not be considered negligible. The fibres can immersed directly in liquid, or placed outside a transparent cell. Three mathematical models are developed these two configurations. It shown that second configuration more advantageous. Experimental measurements tend confirm validity one three models.
