Live Electro-optic Imaging (LEI) for Real-time Analyses of Electric Near-fields over Microwave Circuits
Live electro-optic imaging (LEI) system is described in this paper, which enables the real-time imaging functionality of electrical signals on up to 10 GHz-class circuits in realtime on a screen at video frame rates as high as 30 frames per second. In the system, photonics provides important features of the system: its 100×100-channel parallel detection and the low invasiveness of electrooptic crystal. With the LEI system, novel diagnostic methods are provided through instantaneous and intuitive analyses of RF signal distribution changes. As an example, LEI observation results for a coplanar waveguide with a moving metal plate are presented.
