Zusammenfassung:The invention provides an optical method and apparatus for determining the pH of a tissue. The method includes the step of first irradiating the tissue with optical radiation. The radiation may first pass through skin covering the tissue of interest, or may irradiate the tissue directly. Radiation reflected from the tissue is then collected to determine a reflection spectrum. pH is then determined by comparing this spectrum to a mathematical model relating optical properties to pH of the tissue.
