Abstract

Fourier optics based imaging system for EMI sources is discussed. It is required to decrease undesired emission in order to prevent EMI. To investigate this problem, a visualization of EM emitting fields is very useful. In this paper, we propose a passive imaging system of EM emitting fields based on Fourier-optics. The complex amplitude values of diffracted fields on an entrance pupil are acquired by using a 6-port correlator which acts as an interferometer. Measured EM fields are then processed by a computer and an image is retrieved using Fresnel inverse transform
