To obtain the phases, full sets of reflections are collected with known alterations to the scattering, either by modulating the wavelength past a certain absorption edge or by adding strongly scattering (i.e., electron-dense) metal atoms such as mercury.
Thus, by modulating the wavelength of a laser beam within a few nanometers, one could selectively detect the SRS process.
The present WIB is based on the wave dispersion phenomenon that can modulate the incoming wavelengths into the shorter wavelengths, creating an apparent wave cut-off characteristic in the wave field across WIB installation area.
In order to overcome the typical drawbacks of a conventional Fabry-Pérot interferometer, i.e. low sensitivity sensing spots at the interference extrema and the ambiguity of the displacement direction, the interferometer modulates the laser wavelength (about ±10−3 wavelengths) periodically with a frequency of 12.5 MHz.
Using our technique, it is possible to modulate the EOT spectra through nanohole arrays and the wavelength of light resonantly scattered at the tip of a gold pyramid.
Utilizing very long wavelength transient absorptions of kinetically trapped dark states, we employ molecular modulation schemes that do not simultaneously modulate the background fluorescence.
It is higher at increased elevation, because there is less air mass and greater atmospheric transparency to shorter wavelength radiation, although local climatic conditions, such as cloud cover, can modulate the dosage [ 9].
It helps modulate the speed of neurotransmission.
The above curves modulate the Filter 2 cutoff.
