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 ...

Speckle pattern formation in spatially limited optical systems
Semiconductor Physics, Quantum Electronics & Optoelectronics, 2016 The dependences of statistical parameters inherent to speckle patterns on the object roughness and aperture size have been investigated. The experimental results that confirm theoretical dependence quality within the limits of errors were obtained.
