Abstract
A noninvasive mid-infrared in vivo glucose sensor for use in connection with the skin of a test subject is disclosed. The sensor includes a mid-infrared light source configured to deliver a light beam to the skin of the test subject, a collector element configured to collect backscattered light from the skin and direct it to the detector, and a detector element configured to measure the collected backscattered light from the skin. The mid-infrared light source may be a quantum cascade laser. The sensor may include optical fibers configured to deliver the light beam to the skin of the test subject. The collector element may be an integrating sphere or a bundle of two or more optical fibers. The sensor may also include a probe containing or connecting to optical fibers coupled to the mid-infrared light source and configured to be placed on the skin to take glucose level readings.
