Node-downloadable frequency transfer system based on a mode-locked laser with over 100 km of fiber
Ziyi Jin, Ziyang Chen, Kai Wu +5
To meet the requirements of time-frequency networks and enable frequency downloadability for nodes along the link, we demonstrated the extraction of stable frequency signals at nod…
Source coding model for repeated snapshot imaging
Junhui Li, Bin Luo, Dongyue Yang +3
Imaging based on successive repeated snapshot measurement is modeled as a source coding process in information theory. The necessary number of measurement to maintain a certain lev…
Modeling the behavior of signal-to-noise ratio for repeated snapshot imaging
Junhui Li, Bin Luo, Dongyue Yang +3
For imaging of static object by the means of sequential repeated independent measurements, a theoretical modeling of the behavior of signal-to-noise ratio (SNR) with varying number…
The role of narrowband filtering in improving signal-to-noise ratio of ghost imaging with thermal light background
Dongyue Yang, Junhui Li, Guohua Wu +3
In ghost imaging with narrow-band signal in thermal light background, signal arm filters bring higher value and upper limit of signal-to-noise ratio (SNR), and faster speed to reac…
