Singularities in speckled speckle: Statistics [PDF]
Optics Communications, 2008 Random optical fields with two widely different correlation lengths generate far field speckle spots that are themselves highly speckled. We call such patterns speckled speckle, and study their critical points (singularities and stationary points) using analytical theory and computer simulations.

Simulation of Laser Profilometer Measurements in the Presence of Speckle Using Perlin Noise
Sensors, 2023 In the manufacturing industry, inspection systems play a crucial role in ensuring product quality. High-resolution profilometric sensors have become increasingly popular for inspection due to their ability to provide detailed surface information. However,

Cold Spring Harbor Perspectives in Biology, 2010 Nuclear speckles, also known as interchromatin granule clusters, are nuclear domains enriched in pre-mRNA splicing factors, located in the interchromatin regions of the nucleoplasm of mammalian cells. When observed by immunofluorescence microscopy, they usually appear as 20-50 irregularly shaped structures that vary in size.

Non-Invasive Full Rheological Characterization via Combined Speckle and Brillouin Microscopy
IEEE Access, 2022 Rheology serves to measure the deformation and flow of materials. Its associated quantities, for example, the Young’s modulus, shear modulus, bulk modulus, or longitudinal modulus, are important in the biomedical field, in particular for soft ...

Journal of Medical Ultrasound, 2020 The "snowstorm" sign refers to the ultrasound appearance of motile hyperechoic specks within synovial fluid and has been reported to have a high specificity for gout. We describe three additional etiologies commonly encountered in the rheumatology clinic that can produce a snowstorm: calcium pyrophosphate deposition disease, fibrin collections/rice ...

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 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.

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
