A two-dimensional imager for measuring the electric-field amplitude and phase distribution across an extended spatial region for millimeter and microwave electro-magnetic waves. The imager consists of a small active area within a generally passive structure which measures the electric E-field amplitude and phase information and impresses this information onto an optical beam. The E-field information is measured by converting the optical signal into and electrical signal and demondulating the E-field information from the electrical signal by processing electronics where the electrical signal is conditioned, stored and the data displayed.
