Combining concepts from Doppler-free spectroscopy, coherent quantum control and frequency comb spectroscopy leads to new opportunities for the precision excitation of atomic species with high ...
Astronomical measurements of motion frequently utilize the Doppler effect, observing shifts in wavelength (or frequency) of emitted waves from moving sources, analogous to a changing siren pitch.
To evaluate real-time duplex colour Doppler examination with colour and pulse Doppler ultrasonography (US) (colour Doppler imaging (CDI)) for detection of the retinal detachment from membranous ...
