Construction of a Plane-Grating X-Ray Hologram With the Electron Microprobe

On the possibility of utilizing holographic schemes in X-ray microscopy

“…2b) (Saccocio, 1967;Giles, 1969). The effect of such a mirror in Xradiation is based on the phenomenon of full external reflection from a surface, since n-1-3 < 1.…”

“…2(c) (Giles, 1969;Yokoseki & Suzuki, 1970;Aoki & Kikuta, 1974 Fraunhofer's axial holography scheme yields a lower maximum resolution than the schemes considered above, but it is more convenient. The following values are the characteristic parameters of experimental schemes" zr-~75 cm, zj~30 cm, 21 =8.34/~, 22=0.63, M~m=253.…”

“…Some authors studied the possibility of using schemes with separation of the beams by a Lloyd's mirror for hologram recording (Fig. 2b) (Saccocio, 1967;Giles, 1969). The effect of such a mirror in Xradiation is based on the phenomenon of full external reflection from a surface, since n-1-3 < 1.…”

“…In striving to develop an X-ray holographic microscope with a higher resolution than that of the shadow microscopes, some authors have studied the possibilities of using Fraunhofer's axial holography, which scheme is shown in Fig. 2(c) (Giles, 1969;Yokoseki & Suzuki, 1970;Aoki & Kikuta, 1974). Sufficiently large distances (z,-zj) are used, so that the virtual and real images do not interfere with each other in the reconstruction of the wave front.…”

Applications of holography

“…The easiest type of hologram to record is the in-line Fraunhofer hologram. Giles (1969) showed results on a 5.9 pm diameter glass fibre illuminated with radiation at 114 from a Be KE source. Aoki and Kikuta (1974) extended this method to two-and three-dimensional objects.…”
