Abstract

This report describes an imaging system employing the digital reconstruction of the near fields of an object using the amplitude and phase of the scattered fields measured on a remote plane in the Fresnel zone. This imaging technique is shown to be significantly different from holographic and phased array systems and basically computationally implements a classical lens system having the reconstruction plane parallel or perpendicular to the measurement plane. The theory of the imaging approach is detailed and the method of obtaining a real-time implementation is described. Test data for the first 64x64 element array using PVDF elements and electronic scanning is presented.
