Abstract

The utilization of three-dimensional imaging in science, defense, and industry is becoming increasingly relevant. Lowcost approaches (through appropriate choice of imagers) integrated with fast computer processing speed, allow threedimensional reconstruction of target objects to become readily accessible. Among techniques in 3D image reconstruction, Axially Distributed Sensing (ADS) utilizes elemental images captured only along the sensor's optical axis, greatly simplifying the procedure for proper three-dimensional reconstruction. Axially Distributed Sensing is procedurally different than conventional Integral Imaging techniques (in which sensor(s) are positioned transversely along the field of view), yet fundamentally related through the use of multiple elemental images and geometric optics. More interestingly, three-dimensional image reconstruction allows the imaging of target objects behind occlusions, or in front of difficult (to optically separate) backgrounds. It will be shown that two primary techniques can be utilized in axially distributed sensing to capture the elemental image information needed for reconstruction. This will be demonstrated in a controlled laboratory environment.
