MIXTURE OF 2 INTERFERING BEAMS IN AN X-RAY INTERFEROMETRY

A mixture consisting of completely interfering and non-interfering bea ms, or completely interfering and partly interfering beams in an X-ray interferometer is studied. X-ray interferometric experiments on the m ixture of blocked/non-blocked beams and attenuated/nonattenuated beams showed good agreements with the calculations. A new parameter of the mixing ratio as well as the phase difference of the oscillations are i ntroduced in the representation of the wave held. Poincare: sphere des criptions are also presented.
