Abstract:

An amplitude sensitive optical heterodyne polarimeter was setup in order to monitor noninvasively the aqueous glucose concentration in rabbits eye. A range of the blood glucose from 35 mgdl to 135mgdl was measured in vivo by biological glucose assay BGA, while the optical rotation of the aqueous glucose was measured by a polarimeter simultaneously. The experimental results showed the consistence between these two independent measurements. There was no time delay between the blood glucose and the aqueous glucose when the blood glucose was descending after the insulin was injected It was ill contract to a 10 minutes time delay when the blood glucose wvas ascending. The detection sensitivity of the polarimeter was 4 mgdl in the measurement. Key ords heterodyne polarinieter. glucose noninvasive
