ABSTRACT:
An instant image display element for X-rays or the like comprises a laminate of an optically transparent plate 3, an optically transparent electrode 4, a deformable elastomer layer 5, a flexible insulating mirror film 6, an ionizable liquid 7 which absorbs X-rays and emits positive and negative ions in proportion to the ray intensity, and an X-ray permeable plate electrode 8. When a potential is developed across the electrodes 4, 8 and an X-ray pattern is projected through electrode 8 and into the liquid 7, the emitted ions of one polarity migrate to the mirror film 6, and cause the elastomer layer 5, and the mirror film 6 along with it, to deform in a pattern corresponding to the X-ray pattern. Such deformation may be optically projected for readout by a Schlieren system or the like.
