Disclosed are a method and an apparatus for precision optical measurement of solute concentration and temperature of a transparent liquid. The apparatus includes a vessel ( ) which contains a sample of liquid ( ), the refractive index of which is to be determined, a light source ( ) and a beam position sensor ( ). The vessel ( ) has an entrance side and an exit side, with a known angular relationship therebetween, and is situated in a known ambient The light source ( ) is located so as to cause a beam of light to impinge on the entrance side at an angle with respect to a normal to an outer surface of the entrance side, to pass through the liquid ( ), and to then pass through the exit side, from which it exits at an angle with respect to a normal to an outer surface of the exit side. The beam position sensor ( ) provides data for determining the exit angle thereby permitting the refractive index of the liquid to be determined, based on the angles.

Method and apparatus for optical measurement of concentration and temperature of liquids

An apparatus and method for temperature and concentration measurement at liquid surfaces using reflectance. The apparatus includes a light source which produces a measurement light beam, and also includes a detector. The measurement light beam has a measurement light beam intensity and impinges on the surface of the liquid specimen. It reflects back as a reflected light beam with a reflected light beam intensity which is related to the reflectivity R of the liquid surface and to the measurement light beam intensity. The detector receives the reflected light beam and determines the reflected light beam intensity. Either the temperature or concentration of the liquid specimen can then be determined based on the reflected light beam intensity. The light source can be a coherent light source, such as a laser. A beam splitter can be provided to split the light beam from the light source into a reference light beam and the measurement light beam. The reference light beam is used to compensate for fluctuations in the light source. Temperature measurements can be conducted on a pure liquid or a multi-component liquid with a substantially constant concentration. Concentration measurements can be conducted on a multi-component liquid which is maintained in a substantially isothermal condition. The method of the invention includes causing a measurement light beam with a measurement light beam intensity to impinge on the surface of the liquid specimen; detecting a reflected light beam; and determining either the temperature or the concentration of the liquid specimen. The measurement light beam can be caused to impinge on the surface of the liquid at an angle which enhances the change of reflectivity with respect to temperature or concentration. Detection of the intensity of the light beams can be carried out using photodiodes, amplifier circuitry, and relatively low-cost digital voltmeters.
