Laser-induced speckle scatter patterns in Bacillus colonies
Frontiers in Microbiology, 2014 Label-free bacterial colony phenotyping technology called BARDOT (BActerial Rapid Detection using Optical scattering Technology) provided successful classification of several different bacteria at the genus, species, and serovar level. Recent experiments

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 ...

Clinical applications of laser speckle contrast imaging: a review
Journal of Biomedical Optics, 2019 . When a biological tissue is illuminated with coherent light, an interference pattern will be formed at the detector, the so-called speckle pattern. Laser speckle contrast imaging (LSCI) is a technique based on the dynamic change in this backscattered ...

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.

Speckle Interferometry, Speckle Masking, Speckle Spectroscopy and Speckle Frame Selection [PDF]
International Astronomical Union Colloquium, 1984 AbstractHigh-resolution speckle imaging is one of the most fascinating possibilities of a Very Large Telescope (VLT). Various speckle methods can yield a resolution of about 0.01" with a 8-m to 10-m VLT. As exiting as the resolution is the limiting magnitude of the speckle methods. The limiting magnitude is extremely seeingdependent.

Splicing at the phase-separated nuclear speckle interface: a model
Nucleic Acids Research, 2020 Phase-separated membraneless bodies play important roles in nucleic acid biology. While current models for the roles of phase separation largely focus on the compartmentalization of constituent proteins, we reason that other properties of phase ...

Speckle patterns for DIC in challenging scenarios: rapid application and impact endurance
Measurement science and technology, 2020 Digital image correlation (DIC) is a widely used technique in experimental mechanics for full field measurement of displacements and strains. The subset matching based DIC requires surfaces containing a random pattern.

Speckle filtering of Synthetic Aperture Radar images using filters with object-size-adapted windows
International Journal of Digital Earth, 2018 Speckle degrades the radiometric quality of a Synthetic Aperture Radar (SAR) image. Previous methods for speckle reduction have used a fixed-size window for filtering the entire image.
