The speed of light in a medium is given by the formula: v=dt Since the time (t) taken in both media is the same, we can write: v1v2=d1d2 Substituting the distances: v1v2=2x3x=23 3. Relating Refractive Index to Speed: The refractive index (μ) of a medium is defined as: μ...

where Ih,true{X(T),Y(T);0} is the true X-ray topography 2D projection simulated according formula (10) with the true displacement-field function (11). The intensity Ih,calc{X(T),Y(T);0} is calculated according to formula (10) with trial displacement-field functions according to an ...
For X-ray optics, OASYS integrates diverse strategies via the implementation of different simulation tools (e.g. ray-tracing and wave optics packages). It provides a language to make them communicate by sending and receiving encapsulated data[31]. OASYS itself is an empty container, while applica...
Replies: 12 Forum: Optics S I Kilovoltage Peak role for an X ray tube Hello everyone, while reading about the X ray tube, I came across this: https://radiopaedia.org/articles/kilovoltage-peak In the second paragraph, it is stated that: "The radiation dose to the patient is directly...
As a result, X-ray optics tend to have long focal lengths. The two current facility-class astrophysical missions have focal lengths of 7.5 m (XMM-Newton) and 10.0 m (Chandra). Most X-ray missions use Wolter I type optics (Wolter, 1952) where X-rays are reflected by a paraboloid of ...

4, the signal and resolution are governed by the physics of the x-ray optics. The higher the x-ray flux at the object, the larger the fluorescence signal will be. The useable flux of x-rays at the object is given by F0∝BSsη(NA)2 [Eqn. 2] where BS is the brightness ...
