N2 - We demonstrate an electric field imaging system with a polarized image sensor, and perform equivalent sampling using a global shutter mechanism. We converted the radio frequency signal to an intermediate frequency using the optical heterodyne method and avoid noise in the low frequency band by setting the intermediate frequency higher than the frame rate of the image sensor. We obtained an electric field distribution image of 100 MHz by simultaneously measuring many points at once.
