Abstract :
We report on instantaneous microwave transmission imaging experiments using a photonic technique. A high-resolution electro-optic (EO) camera we developed was used as a microwave image sensor under near-field conditions. Microwave transmission images of water capsules could be depicted with 10,000 pixels in less than one second. The images using a combination of the observed microwave intensity and phase showed higher contrast. The spatial resolution was as fine as one tenth of the microwave wavelength. Our system is potentially applicable to microwave transmission imaging of aqueous objects and their diagnoses.
