METHOD AND APPARATUS FOR VECTOR MEASUREMENT OF RADIATING ELECTROMAGNETIC WAVES

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus where the distribution state of radiated electromagnetic waves, in a range which is comparatively close to electrical component is measured simply.;SOLUTION: The measuring method for the vector of the radiated electromagnetic waves comprises steps which includes a step of preparing light detection means having a plurality of light detecting elements arranged inside a plane by keeping a definite positional relationship, an arrangement step in which the light detection means are arranged in a plurality of required specific positions with reference to an object to be measured, a photoelectric conversion detection step, in which light intensities generated in the respective light detecting elements at the light detection means are fetched to respective electrical signals in the respective specific positions and a computing step in which the output of the photoelectric conversion detection step is converted into a digital signal, so as to be computed and in which an electric-field vector in an arbitrary specific point of the object to be measured is computed.;COPYRIGHT: (C)2003,JPO
