Abstract

A device for measuring the inside information of a light-scattering specimen using a Line Spread Function (LSF) function of a light-scattering specimen and the intensity distribution of light which is transmitted through the light scattering specimen in repeating light scattering and output from the light scattering specimen. The device comprises: an optical system for illumination for irradiating a specimen to be measured (a light scattering specimen); an optical system for detection for detecting the transmitted light through the specimen; and a data processor for operating the detected transmitted light data. The above-mentioned data processor operates the inside information of a specimen to be measured based on the light intensity distribution of the transmitted light through the specimen and an LSF function which is newly defined, and displays the inside information as a tomograph image.
