Deep NIR imaging of galaxy clusters in the Vela supercluster
… the shorter optical wavelengths, near infrared (NIR) observations are less affected by dust obscuration in the ZoA and therewith offer a better tool to probe galaxy clusters in the VSCL, and get a better understanding of this extended supercluster. A series of deep NIR observations of prospective …

Low-noise image sensor designed for near-infrared image-guided surgery
… of a physician. X-ray, magnetic resonance imaging (MRI), and near-infrared (NIR) fluorescence are a few categories of medical imaging that are capable of gathering information from below the skin surface. NIR fluorescence imaging is very compatible with the needs of medical imaging. NIR …

Minimally invasive assessment of lymphatic pumping pressure using near infrared imaging
… counterpart. Recent advances in optical imaging techniques have allowed for more detailed and quantitative evaluations of lymph flow dynamics and mechanism. A rat tail is often used for investigations of lymph flow because of the simple geometry, superficial nature, and disease …

Imaging skin structures for health, body mapping, and identification (under the Tucson Skin)
… body and the 3D non-rigid nature of the body. Imaging the vasculature is difficult as it is below the skin surface. Current optical imaging technology to penetrate the skin surface is expensive. Image processing algorithms often incorrectly identify the subdermal features, mistaking the veins …
