Abstract:
1. An apparatus for determining the concentration of chiral molecules in a fluid comprising: a first polarizer configured to polarize light substantially in a first plane; a second polarizer configured to polarize light in a plurality of planes, at least one of the plurality of planes being different from the first plane, wherein the second polarizer includes a polarizer array including one or more polarizing elements, each of the one or more polarizing elements configured to polarize light substantially in a respective single plane, each of the respective single planes being different from one or more of the other of the respective single planes; a fluid chamber, at least a portion of the fluid chamber at least partially disposed between the first polarizer and the second polarizer, the fluid chamber configured to retain a volume of fluid; and at least one receiver capable of measuring an intensity of incident light transmitted through the first polarizer and through the second polarizer, wherein the concentration of chiral molecules in the volume of fluid is determined using the intensity of incident light transmitted through the first polarizer and through the second polarizer.
