METHOD AND APPARATUS FOR DETERMINING WAVE CHARACTERISTICS USING INTERACTION WITH A KNOWN WAVE

摘要

The described system and method uses data from interaction between a known wave and an unknown wave to analyze or characterize the unknown wave using cross correlation frequency resolved optical gating (X-FROG). The system may obtain X-FROG trace data from the interaction between the two waves. The system analyzes the X-FROG trace data using a modified principal component generalized projection method strategy to invert the X-FROG trace data, analyzing or characterizing the unknown wave. Results of the analysis can be provided in real time and displayed.

1. A method for determining characteristics of an unknown wave comprising:
providing wave phenomena data wherein the wave phenomena data comprises a reversible transform of a product of at least two waves, wherein one of the waves is known a priori and another of the waves is unknown; and determining characteristics of the unknown wave from the wave phenomena data by converting the known wave into the unknown wave, wherein the determining includes combining a vector representing the known wave with a vector representing an initial guess for the unknown wave.
