In Vivo, Noninvasive Glucose Monitoring With Optical Heterodyne Polarimetry in a Range of 50 mg/dl ^ 100 mg/dl
Abstract
An amplitude sensitive optical heterodyne polarimeter was setup in order to monitor noninvasively the aqueous glucose concentration in rabbit's eye. A range of the blood glucose from 35 mg/dl to 135mg/dl 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 mg/dl in the measurement. Key %ords : heterodyne polarinieter. glucose noninvasive
