摘　　要：对目前实际可获得的台式激光等离子体X射线光源各种性能进行了分析 ,论证了利用这类设备获得有实际应用价值的X光全息图的可行性。并在此基础上进行数值模拟 ,讨论了各种参数对实验结果的影响 ,讨论了缩短实验时间及获得更高分辨率的可能途径。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 by 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.
