Abstract
Methods and apparatus for normalizing path length in an optical system for non-invasive glucose concentration. A method arrangement includes providing an optical energy source spaced from a first photo-detector by a sensing area; transmitting energy from the optical energy source onto the first photo-detector; storing a first reading corresponding to the light intensity observed by the first photo-detector; subsequently, introducing a container of solution including an optically active substance into the sampling area; transmitting energy from the optical energy source through the container in the sampling area and onto the first photo-detector; storing a second reading corresponding to the light intensity observed by the first photo-detector; determining a ratio of the first reading to the second reading; and determining a path length L by computing L=ln(ratio)/μ where μ is an absorption constant of the optical energy in the solution and container. Additional arrangements are disclosed.
