Method and apparatus for measuring concentration of absorptive constituent in scattering medium |
摘要 |
<p>A method for measuring a concentration of an absorptive constituent in a scattering medium comprises the steps of emitting two or more kinds of light having predetermined wavelengths; making said light incident at a light incidence position into said scattering medium; detecting said light at one or more photodetection points to acquire one or more photodetection signals; detecting light quantities and average flight pathlengths for said respective kinds of light based on said signals; and obtaining a concentration of said absorptive constituent by arithmetic processing using said light quantities and average flight pathlengths based on a predetermined relationship. The method permits absolute-value measurement of the concentration of the absorptive constituent inside the scattering medium having various exterior shapes. <IMAGE></p> |
