    摘要: The invention concerns in particular, an instrument for measuring the refractive index of a fluid, particularly seawater. Its object is more specifically an instrument for measuring the refractive index of a fluid having a sensor machined to contain the fluid whose refractive index is to be measured, a coherent light source which illuminates the sensor via at least one beam of coherent light, a photodetector, and processor means with which the refractive index of the fluid can be determined from the interference fringes produced by transmission and/or reflection interferences of the beam at the various optical interfaces of the sensor.
