Sensing with Fractal, Diffraction-encoded Beams
Abstract
The proposed research aims to advance knowledge and identify the limits of optical environmental sensing with self-similar, fractal-encoded beams. In the scheme that enables such sensing, the transmitted kernel patterns are iteratively mixed and spatially distributed over large areas so that a portion of the beam may be sampled to reconstruct the kernel. The PI has recently demonstrated alignment-agnostic sensing with self-similar Cantor fractals, which are binary-valued fractals. With Cantor fractals, the redundant information in the propagated fractal beam provides immunity to misalignment, adverse, or noisy environmental conditions; Cantor-fractal approaches also present new concepts for robust channel marking and simple schemes for compressed sensing.
