Improvement of the signal-to-noise ratio in digital holography
(Sociedad Mexicana de Fisica, 2005-01-01)
A fundamental problem in optical and digital holography is the presence of speckle noise in the reconstruction process, which essentially diminishes the signal to noise ratio (SNR). For many applications, that reduction ...

Experimental demonstration of a noise-tunable delay line with applications to phase synchronization
(Elsevier Science, 2015-05)
In this paper we propose and demonstrate a discrete circuit capable of generating arbitrary time delays dependent on noise, either added externally or already present in the signal of interest due to a finite signal-to-noise ...
Improvement of the signal-to-noise ratio in interferometry using multi-frame high-dynamic-range and normalization algorithms
(ELSEVIER SCIENCE BV, 2012-01-01)
Using both high dynamic range (HDR) and normalization methodologies, we show a method to improve the fringe pattern contrast in interferometric measurements normally used for phase recovering. In a simulated interferogram ...
