3D imaging provides important profile information not available with conventional 2D image products. Profile information can be extremely valuable for industrial- inspection and remote target-characterization applications. In this paper, we discuss a novel imaging modality, called PROCLAIM, that utilizes the powerful constraint that opaque objects can be described by a 2D surface embedded in 3D space. Far-field Fourier intensity measurements are collected by flood-illuminating an object with a frequency- tunable laser and direct detecting the backscattered signal with a lensless sensor. This technique allows for precise, non-contract surface measurements, without the stringent coherence and mechanical stability requirements of related interferometric techniques. We present reconstruction results form simulated data and from laboratory measurements.
