Abstract
Biochemical components and changes in the components are measured by directing light of several wavelengths into a body at one location, sensing light at the wavelengths emerging from the body at a plurality of distances from the one location, and ascertaining biochemical component characteristics in the body as a function of variations, with respect to distance, of the logarithm of the ratio of the light sensed to the light directed into the body. The variations with respect to distance are in the form of the derivative and square of the derivatives of the logarithm.
