Implantable chemical sensor with rugged optical coupler |
摘要 |
A method and apparatus is provided for determining a property of an analyte using a sensing layer whose optical response changes with the analyte. The apparatus includes a housing with an optically transparent window for receiving the sensing layer. The window passes optical stimulation to the sensing layer and the optical response from the sensing layer. A stimulating light emitter is coupled to a first face of an optical body monolithically coupled to the window and a light detector is coupled to a second face of the optical body for receiving the response. The optical response changes as the concentration of the analyte changes. Reference molecules included in the sensing layer can provide a calibration signal to a second light detector mounted on a third face of the optical body. The first, second and third faces of the optical body are different and not coplanar.
