Surface roughness evaluation of additive manufactured metallic components from white light images captured using a flexible fiberscope

Application of EMCCD in the small-optical fiber endoscope imaging detection system

“…Optical fiber endoscope can flexibly insert the body cavity of human or animals, and perform optical endoscopic of hidden parts in the body that are not easily observed by the naked eye. By collecting tissue or cell specimens to provide image information of lesions for diagnosis of diseases [1,2], it has been widely used in clinical diagnosis of humen intestine, stomach and other cavity organs, as well as surgery for polyps and tumors. Endoscopic and appropriate biopsy are the criteria for early detection of cancer and judgment of lesions [3,4].…”

Large Area Metal Surface Characterization using Plasmonic Random Laser based Imaging Technique

“…Surface topography measurements are essential for many engineering applications, especially for testing and calibration of components [1,2]. Optical imaging techniques such as interferometry and confocal microscopy are the most commonly used methods due to their non-contact and non-destructive capabilities [3][4][5][6]. Interferometric microscopes analyze the interference fringes formed by coherent illumination to track the peaks and valleys of the surface texture and produce digitized topography profiles and images.…”
