Speckle-interferometry and speckle-correlometry of GB-speckles
Frontiers in Bioscience, 2019 A new method of coding of genetic information using laser speckles has been developed. Specific technique of transforming the nucleotide of gene into a speckle pattern (gene-based speckles or GB-speckles) is suggested. Reference speckle patterns of omp1 gene of typical wild strains of Chlamydia trachomatis of genovars D, E, F, G, and J are generated ...

Towards Reduced CNNs for De-Noising Phase Images Corrupted with Speckle Noise
Photonics, 2021 Digital holography is a very efficient technique for 3D imaging and the characterization of changes at the surfaces of objects. However, during the process of holographic interferometry, the reconstructed phase images suffer from speckle noise.

Phase extraction in dynamic speckle interferometry: proposal of a road map
EPJ Web of Conferences, 2010 Of all the two-beam interference patterns, the ones obtained in speckle interferometry (SI) are the most difficult to be phase-demodulated. Many solutions exist in classical smooth-wave interferometry and alike techniques, both in static and dynamic ...

Experimental assessment of determining the average size of speckles
Вестник Самарского университета: Естественнонаучная серияThe paper proposes a method for estimating the average speckle size using experimentally recorded images of speckle fields on a CMOS matrix. This method can be useful when used in speckle interferometry methods when determining their metrological ...

Advanced Science, EarlyView.This review introduces the concept of “general curvy surface reconstruction,” which incorporates both geometric and physical dimensions, representing an upgrade over conventional geometric reconstruction that focuses solely on spatial relationships. Particular emphasis is placed on the emerging opportunities enabled by advanced measurement techniques ...
