Abstract: A radiation detector includes a plurality of detector elements arranged on a detector substrate in an interdigitated linear array. A thermoelectric or other cooler is attached to the lower surface of the detector substrate. A pair of interconnect boards is positioned on opposite sides of the detector substrate. The detector elements, substrate, cooler and pair of boards are received in a sealed housing and a radiation transmitting window in the housing permits radiation to pass into the housing and strike the detector elements. A plurality of conductive pins extends through the housing and terminates at electrical traces on the interconnect boards. A thermistor or other temperature sensor is attached to the detector substrate and, through control of the thermoelectric cooler, maintains the detector substrate at a desired operating temperature.

Abstract: A method and apparatus (12) for the non-invasive sensing of blood glucose levels includes apparatus (10) which moves the forearm of the patient in a controlled incremental manner to take a plurality of spectral skin measurements and averaging the measurements for the purpose of accounting for biological differences that exist in the patient's skin.
