... assume that we have an additional point source at P. As the light travels equally well from P to S as from S to P, the intensity at the point S consists also of contributions from P, and not only from F. The contribution from P is weaker than that of F because it is weighted by h( u , v ), with u , ...

We must also stress that the logarithmic axis for q is essential as well as q itself because so much of our world progresses geometrically rather than arithmetically. We call this procedure of plotting scattered intensity versus q double logarithmically “Q-space analysi ...

Retroreflector



A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
