WebApr 11, 2024 · In such cases, incoherent components should be used to estimate the roughness. As it has been presented in Section 4.1, the coherent component and the total power waveform present a ~−9 dB consistent bias and an ubRMSD of 3.4 dB. Computing the roughness with coherent or incoherent components might impact a bias in the … Webcoherence) – imaging methods based on statistical properties of light: coherence imaging, coherence tomography • Inverse Problems – to what degree can a light source be determined by measurements of the light fields that the source generates? how much information is “transmitted” through an imaging system?
