Abstract
The present invention relates to viewing a three-dimensional internal structure of a specimen. According to the invention, it is possible to observe the internal structure of a particular cross section of a specimen as clearly differentiated from the other cross sections. The characteristic features of the invention lie in that a plurality of light beams passing through different portions inside the specimen are used, and a correlation among the measurements of transmittance of the plurality of light beams is determined.
