Claim Text:
1. A noninvasive apparatus for measuring glucose, the apparatus comprising: a housing having at least a first region and a second region, the first region and the second region separated by a space; an energy source emitting an optical signal, the energy source positioned in the first region of the housing; a first optical polarizing unit for polarizing at least a portion of the optical signal to provide a first polarized energy, the first optical polarizing unit positioned in the first region of the housing; a second optical polarizing unit for polarizing at least a portion of the first polarized energy to provide a second polarized energy, the second optical polarizing unit positioned in the second region of the housing; a first optical detection unit for detecting at least some of the first polarized energy, the first optical detection unit positioned in the second region of the housing, the first optical detection unit having an output; a second optical detection unit for detecting at least some of the second polarized energy, the second optical detection unit positioned in the second region of the housing, the second optical detection unit having an output; and a circuit interfaced with and receiving the outputs of the first and second optical detection units, the circuit determining a glucose concentration.
