摘要

基于数字体相关的光学相干弹性成像（DVC-based OCE）容易受到光学相干层析成像（OCT）的乘性散斑噪声的影响，从而导致不可忽略的计算误差。本研究采用Hamilton-Jacobi偏微分方程对OCT图像进行乘性去噪，研究乘性去噪对基于dvc的OCE的影响。测试了静态、亚像素平移、均匀压缩和非均匀变形等几种变形条件。结果表明，在静态测试中，乘性噪声去除可以将最大噪声误差抑制到0.15像素以下。得到了更精确的亚像素平移，精度为0.6像素。对于均匀压缩，乘性去噪可以将应变上限扩展到0.116，误差小于15%，相关值大于0.8。在非均匀变形情况下也有较好的效果，计算点更可靠。这些发现为通过去除OCT图像上的乘性噪声来提高基于dvc的OCE方法的测量精度提供了一种方法。

Impact of multiplicative noise removal on digital volume correlation-based optical coherence elastography

Digital volume correlation-based optical coherence elastography (DVC-based OCE) may easily suffer from multiplicative speckle noise of optical coherence tomography (OCT) imaging, which can introduce non-negligible calculation errors. In this study, Hamilton-Jacobi partial differential equations were adopted for multiplicative noise removal of OCT images and the impact of multiplicative noise removal on DVC-based OCE was investigated. Several deformation conditions, including static, sub-pixel translation, uniform compression and non-uniform deformation, were tested. Results showed that multiplicative noise removal can suppress the maximum noise-induced error to less than 0.15 pixels in static tests. A more precise sub-pixel translation with an accuracy of 0.6 pixels was obtained. For uniform compression, multiplicative noise removal can extend the strain upper limit to 0.116 with an error less than 15% and a correlation value higher than 0.8. It also worked better in non-uniform deformation with more reliable calculation points. These findings provide a way to improve the measurement accuracy of the DVC-based OCE method by removing multiplicative noise on OCT images.

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
