The role of narrowband filtering in improving signal-to-noise ratio of ghost imaging with thermal light background
arXiv:1602.03949
Abstract
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 reach that limit. The narrower bandwidth, the better.
