Speckle pattern processing by digital image correlation [PDF]
MATEC Web of Conferences, 2016 Testing the method of speckle pattern processing based on the digital image correlation is carried out in the current work. Three the most widely used formulas of the correlation coefficient are tested.

Hyperuniformity in amorphous speckle patterns [PDF]
Optics Express, 2018 Hyperuniform structures possess the ability to confine and drive light, although their fabrication is extremely challenging. Here we demonstrate that speckle patters obtained by a superposition of randomly arranged sources of Bessel beams can be used to generate hyperunifrom scalar fields.

Image-Enhanced Pseudo-Thermal Ghost Imaging with Hybrid Speckle Pattern
Photonics, 2023 In this study, the influence of hybrid speckle patterns on the contrast-to-noise ratio (CNR) and resolution in pseudo-thermal ghost imaging (PGI) was examined based on the object dimensions in the macroscopic and microscopic regimes.

Improvements of Computational Ghost Imaging by Using Sequenced Speckle
Applied Sciences, 2023 This study presents a computational ghost imaging (GI) scheme that utilizes sequenced random speckle pattern illumination. The primary objective is to develop a speckle pattern/sequence that improves computational time without compromising image quality.

Different methods for characterizing surface roughness using laser speckle technique
Iraqi Journal of Physics, 2019 In this work, results from an optical technique (laser speckle technique) for measuring surface roughness was done by using statistical properties of speckle pattern from the point of view of computer image texture analysis.
