In digital coherent imaging and measurement systems, the image/fringe pattern quality is severely degraded by multiplicative uncorrelated noise, called speckle, resulting due to the coherent nature of the light source, which restricts the development of several applications of these systems in various fields. Digital holography, holographic interferometry, speckle metrology, and shearography are the most revealing non-invasive imaging and measurement tools in many areas including scientific, engineering, biomedical, and industrial applications. However, the presence of undesired speckle noise in the processed image/phase distribution may lead to ambiguity in the observation or analysis of the associated physical parameters, and thus, limit their applications in many fields. To overcome this problem, a variety of algorithms/methods/techniques have been developed to eliminate the inherent speckle-noise introduced in the images/phase distribution obtained from these systems, depend...

成像系统中的斑点去噪技术

在数字相干成像和测量系统中，由于光源的相干特性，被称为斑点的乘法不相关噪声严重降低了图像/条纹图案的质量，这限制了这些系统在各个领域中的几种应用的发展。在包括科学，工程，生物医学和工业应用在内的许多领域中，数字全息，全息干涉术，散斑计量学和剪切成像是最揭示非侵入性成像和测量工具。但是，在处理后的图像/相位分布中不希望有的斑点噪声的存在可能导致相关物理参数的观察或分析不明确，因此限制了它们在许多领域中的应用。为了克服这个问题，
