ABSTRACT:
The presence and concentration of an optically active constituent of a fluid medium is determined in-situ by immersing in the fluid medium a probe constructed to pass plane polarized light through the fluid medium in first and second passes so as to induce an optical rotation to the plane of polarization. The light is analyzed after the second pass in a manner to provide a plurality of light components whose individual intensities are affected by the induced optical rotation. A light intensity ratio is determined for the individual light components and compared to light intensity ratios obtained from like fluid media having known concentrations of the optically active constituent therein to permit determination of the concentration of the optically active constituent.
