12 results about "Phase retrieval" patented technology

Phase retrieval is the process of algorithmically finding solutions to the phase problem. Given a complex signal F(k), of amplitude |F(k)|, and phase ψ(k): F(k)=|F(k)|eⁱψ⁽ᵏ⁾=∫₋∞∞f(x) e⁻²πⁱᵏ·ˣ dx where x is an M-dimensional spatial coordinate and k is an M-dimensional spatial frequency coordinate. Phase retrieval consists of finding the phase that satisfies a set of constraints for a measured amplitude.
