Abstract : The electromagnetic energy is captured by the antenna and changes the reflectivity of a Liquid Crystal Display (LCD) proportional to the field being measured. The LCD is illuminated by a fiber optic and this light is reflected from LCD proportional to the electromagnetic field. This field proportional light is captured by a fiber optic and transmitted to a photodetector where it is converted to an electrical signal proportional to the electric field. This electrical signal may then be displayed, recorded or processed with other information. (Author)
