An examination apparatus for examining with transmission photometry an object of interest. The apparatus comprises: light launching means for successively launching an incidence light beam to the object at an incidence site; and light pickup means for picking up, in synchronism with launching of the incidence light beam, light beams scattered in the object from a plurality of output sites as light intensity data, and performing mathematical processing on the light intensity data for every launching of said incidence light beam to obtain absorption data representing a light absorption quantity at the incidence site.
