Abstract
An apparatus and method for noninvasively measuring blood glucose concentration. The apparatus disclosed uses light pulses directed onto a patient's skin and reflected back from the patient to measure blood glucose. Reflected light is passed through light filters that transmit a narrow bandwidth of light within a range of wavelengths that is absorbed by glucose and then measured. Unreflected light is passed through identical light filters and also measured. The two measurements are then compared and used to calculate the patient's blood glucose concentration.
