In the case of a volume hologram (or Bragg hologram), the Bragg condition occurs and hence Bragg diffraction in the formation of the image, as the optical path difference between wavefronts reflected from successive layers of material (photopolymer in this case) is an integral multiple of the wavelength.

The XRD analysis of this silica xerogel was performed by using Scherer equation in the form, D = kl/Bcosth, where the shape factor k is equal to 0.89, th is the Bragg diffraction angle, l is the wavelength of X-rays having value equal to 1.5418 A and B is the full width of the observed peak at half maximum (FWHM).

It can be clearly seen that the curves of M-PPS, HTM-PPS, and 12hM-HTM-PPS are identical to each other, showing all crystalline Bragg diffraction. However, FHTM-12hM-PPS shows the characteristic of no crystalline Bragg diffraction and has only a broad amorphous diffraction.
