Surface characterization of biodegradable nanocomposites by dynamic speckle analysis
Applied Surface Science Advances, 2023 Starch/kefiran/ZnO nanocomposite films may exhibit different physicochemical properties depending on the distribution of ZnO nanoparticles. As a result of UV exposure, the hydrophobicity of the nanoparticles may be modified, resulting in their dispersion

Effect of Speckle Size on the Correlation of the Superposed Speckle Patterns
13th International Conference on Fiber Optics and Photonics, 2016 Effect of the size of constituent speckles on the intensity correlation of mixed speckle pattern due to superposition of speckles from two different scatterers is investigated experimentally using off-axis holographic technique.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Studies on deep learning dose prediction increasingly focus on 3D models with multiple input channels and data augmentation, which increases the training time and thus also the environmental burden and hampers the ease of re‐training. Here we compare 2D and 3D U‐Net models with clinical accepted plans to evaluate the appropriateness of

Speckle Decorrelation and Dynamic Range in Speckle Noise Limited Imaging [PDF]
arXiv, 2003 The useful dynamic range of an image in the diffraction limited regime is usually limited by speckles caused by residual phase errors in the optical system forming the image. The technique of speckle decorrelation involves introducing many independent realizations of additional phase error into a wavefront during one speckle lifetime, changing the ...

Algorithm for dynamic Speckle pattern processing
Optics and Lasers in Engineering, 2016 Abstract In this paper we present a new algorithm for determining surface activity by processing speckle pattern images recorded with a CCD camera. Surface activity can be produced by motility or small displacements among other causes, and is manifested as a change in the pattern recorded in the camera with reference to a static background pattern ...
