1. A noninvasive system for measuring glucose, the system comprising:

  • a light source for emitting light capable of penetrating body tissue;

    a first polarizer proximal to the light source for receiving all or at least a portion of the light emitted from the light source and for providing a first polarized light;

    a second polarizer spaced apart from the first polarizer and positioned in a manner to receive polarized light provided by the first polarizer after the all or at least a portion of the light passes through the first polarizer to provide a second polarized light;

    a first detector positioned in a manner to detect at least some or all of the first polarized light; and

    a second detector positioned in a manner to detect at least some or all of the second polarized light;

    one or more of the first detector and the second detector being so adjusted, the adjusting comprising at least one of increasing, decreasing, and comparing, a first output of the first detector and a second output of the second detector, to determine a relative intensity of the first polarized light relative to the second polarized light or the second polarized light relative to the first polarized light.
