Abstract
A method of measuring the intensity of radiation transmitted through a body of given shape and material, the method including the steps of directing an incident beam of electromagnetic radiation crosswise onto the body to obtain an output beam coaxial with the incident beam; and measuring the energy of the output beam by correcting the energy transmitted by each of the rays of at least one of the two beams as a function of the length (d) of an optical path through the body and aligned with the ray.
