Abstract

We introduce a millimeter wave imaging modality with extended depth-of-field that provides diffraction-limited images with reduced-spatial sampling. The technique uses a cubic phase element in the pupil of the system and a nonlinear recovery algorithm to produce images that are insensitive to object distance. We present experimental results that validate system performance and demonstrate a greater than four-fold increase in depth-of-field with a reduction in sampling requirements by a factor of at least two.
