On the Formulation of Coded Demodulation and 3D Reconstruction in Rotating PB-ToF sensors

The use of Time-of-Flight cameras has been recently popularized due to the relatively low-power consumption and manageable size. However, the optical system imposes a restriction in the field of view of the camera and motion artifacts appear in unsteady environments. In this paper, we present a novel sensing system that enables flexible trade-offs between the field of view and the lateral resolution, no longer fixed by the array geometry, in close to real-time operation. Our approach is based on the introduction of a controlled rotation during sensing. As a result, we propose an original sparsity-aware greedy algorithm for 3D reconstruction. The novel computational sensor is validated via numerical simulations.
