Imaging processes and coherence in physics

Witryna5 maj 2024 · Phase Coherence Imaging was proposed in 2009 as a new adaptive beamforming method, based on measuring the instantaneous phase dispersion of the aperture data. Low phase dispersion is indicative of a focused reflector, while large phase dispersion is produced by out of focus reflectors, reverberations and the grained … WitrynaOn October 4, the Nobel Prize in Physics 2024 was awarded to Alain Aspect, John F. Clauser and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science". Their results have cleared the way for new technology based upon quantum information.*.
