Claim:
1. A noninvasive system for measuring glucose, the system comprising: a light source emitting light in one of a red wavelength, near infrared wavelength, and an infrared wavelength, the light being 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 directly from the light source; 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, such that the second polarizer provides a second polarized light; a first detector positioned in a manner to detect at least some or all of the polarized light, in which the polarized light is polarized only from the first polarizer; and a second detector positioned in a manner to detect at least some or all of the second polarized light, in which the second polarized light is provided by a first polarization with the first polarizer followed by a subsequent polarization with the second polarizer; the first detector being position proximal to the second detector, and one or more of the first detector and the second detector being so adjusted that the polarized light to the first detector is of a similar intensity as that of the second polarized light to the second detector.
