Ray Diagram Various optical instruments, such as telescopes, microscopes, cameras, and corrective eyeglasses, use lenses to function. Lenses are optical devices that use refraction or bending of light to form an image. There are two types of lenses — concave lens and convex lens. A convex, ...

and the total reflection from the inner surface guides the X-ray to the focus. XRF analysis while scanning the specimen additionally provides elemental distribution images. A schematic diagram of micro-focused XRF equipment is shown inFig. 2. Spatial resolution, which depends on the focus size, ...
Procedures such asendoscopy,laparoscopy, andcolposcopymake use of generally flexible optical instruments that can be inserted through openings, either natural or surgical in origin, in the body. Many scope instruments are fitted with small video cameras that enable the physician or surgeon to view the...
The section of the tube from which the beam emerges includes the heater, cathode, grid and the first accelerating anode; these collectively form the electron gun. A simplified diagram of the connections is given in Figure 11.13. The electric field of the relatively positive anode partly penetrates...
As for the focusing optics, the fol- lowing optical instruments are often used: (a) glass capillary, which selects the beam with a divergence angle smaller than the critical angle of inner glass sur- face, (b) a Kirkpatrick-Baez (K-B) focusing mirror system,37 which consists of two ...
X-ray luminescence tomography (XLT) is a recently developed modality that combines the high spatial resolution of X-ray imaging through tissue with the chemical sensitivity of optical indicators [1,2]. It relies on phosphors injected or implanted in the tissue, which serve as contrast agents that...
The Feynman diagram for the photon-axion interaction is shown in the bottom central panel of Figure 2. We used the example of a gamma-ray converting into an ALP in the magnetic field of a galaxy cluster that might harbor the blazar. The ALP can then convert back into a gamma-ray in, ...
National Instruments offers high-performancePCI and PXI FlexRay interfacesfor connecting PCs to FlexRay networks. With a PC-based interface, you can perform many engineering tasks on a FlexRay-enabled ECU, including: Rapid Prototyping Hardware-in-the-loop simulation ...
