Abstract
Different property parameters of practically available table top laser plasma X ray source are analyzed theoretically, and the feasibility of making valuable X ray hologram using these kinds of facilities is proved. On the basis of these achievements, in line holography and image reconstruction are programmed and simulated. Parameters including X ray coherence, signal to noise ratio, source intensity and recording length that can influence experimental result are discussed. Furthermore, the possible methods to reduce exposure time and to acquire higher resolution are studied.
