METHOD OF EVALUATING INSIDE OF OBJECT BY TRANSMITTED LIGHT

摘要

A method of evaluating the inside of an object, wherein a linearly polarized light is applied to an object, and the light passed through the object is admitted to a polarizer having a transmission axis parallel to the polarization of the applied light to detect it on the optical axis of the applied light and thereby remove a scattered light from the object, thereby obtaining an image dependent on the intensity of a transmitted light free from the effect of a scattered light. Further, a method of evaluating the inside of an object, wherein the intensity of a transmitted light is measured and computed by a plurality of wavelengths of a material contained in an object and having different absorption coefficients to thereby obtain an image emphasizing that material only, or the intensity of a transmitted light is measured with the object kept rotated to thereby obtain a 3-D light image inside the object.
