Evaneszente feld
Tīmeklis2024. gada 16. marts · We propose an evanescent-field interferometer in the Mach-Zehnder configuration, which can provide an interferometric measure of the phase of evanescent fields and can be used to quantify the Hartman effect. The phase difference for such tunneled fields saturates to $\\ensuremath{\\pi}/2$, thus … TīmeklisTotal internal reflection fluorescence microscopy ( TIRFM) exploits the unique properties of an induced evanescent wave or field in a limited specimen region immediately adjacent to the interface between two media having different refractive indices. In practice, the most commonly utilized interface in the application of TIRFM …
