Abstract :
A novel electric-field scanner (E-Scan) allows us to obtain two-dimensional electric-field images in a short time by scanning with a laser beam. Measurement time with E-Scan is decreased by more than one order compared to previous electric-field mapping systems. We have demonstrated measurement of antenna radiation patterns and millimeter-wave imaging with E-Scan.
