Abstract
In the method and apparatus for inhibiting a scattered component in a light having passed through the interior of an examined object, a light is radiated to the examined object, the sum of a straight advancing light component and scattered light component of the light having passed through the interior of the examined object is detected, only the scattered light component of the light having passed through the interior of the examined object is detected and the straight advancing light component is detected by an operation using the two detected outputs. In the scattered component inhibiting method and apparatus, a light modulated with a period larger than the delay of the propagating time by the scatter in the examined object is radiated to the examined object, the light having passed through the interior of the examined object is detected and the straight advancing light component is extracted by extracting a predetermined phase of the detected output. Or, in the scattered component inhibiting method and apparatus, a light of a plurality of wavelengths is radiated to the examined object, the light having passed through the interior of the examined object is detected and the scattered light component is inhibited by an operation using a plurality of detected outputs corresponding to the detected plurality of wavelengths.
