在分析了光源相干相体积的基础上,重点研讨了第三代同步辐射中波荡器(undulator)辐射的相干模式,能谱亮度,相干光子通量等。这对提高光束线相干能量的传输效率和软X光相干光学束线的设计具有重要意义。

Coherence light source with high brightness has important promising in the applications of X ray holography, three dimension imaging and X ray microscopy. On the basis of coherence phase volume analysis, the coherence mode, spectral brightness and photon flux etc. for undulator source in the third generation synchrotron radiation are illuminated in detail. It is important to the improvement of the efficiency for coherence energytransmission and of the soft X ray beam line design for X ray coherence experiments.
