WebSep 7, 2024 · DeMaH mainly involves four steps: blood vessels removing, depth mapping generation, feature mapping fusing, and segmentation network embedding. In the first step, vessels are removed and substituted using the nearest neighbor interpolation. In the … In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one material to … See more In most areas of optics, and especially in microscopy, the numerical aperture of an optical system such as an objective lens is defined by $${\displaystyle \mathrm {NA} =n\sin \theta ,}$$ See more A multi-mode optical fiber will only propagate light that enters the fiber within a certain range of angles, known as the acceptance cone of the fiber. The half-angle of this cone is called the acceptance angle, θmax. For step-index multimode fiber in a given … See more • "Microscope Objectives: Numerical Aperture and Resolution" by Mortimer Abramowitz and Michael W.
