Abstract
A method and apparatus for calibrating an NIRS system which includes a sensor portion and for evaluating an NIRS system for proper functioning is provided that includes an enclosure with at least two windows disposed in a wall of the enclosure. The windows allow the light source and one or more detectors of an NIRS system sensor to interface with the enclosure. One window is dedicated to the light source while each light detector has a window dedicated thereto. Thus, the enclosure includes a number of windows equal to the number of light detectors in the NIRS system sensor plus one. The inner surface of the wall(s) of the enclosure is of a light-absorbing color; e.g., black. A diffuse reflectance member of a light-reflecting color, e.g., white, is disposed in the enclosure spaced apart from the surface with the windows disposed therein.
