Li Jinghong, Peng Huimin, Zhang Guoping, Lei Guangyu

CHINESE JOURNAL OF COMPUTATIONAL PHYSICS 1997, 14 (S1): 421-423.

Abstract （205）

PDF （144KB）（974）

Based on the theoretical study of spatial coherence of laboratory x-ray lasers, a principle setup is proposed for x-ray laser holography, and corresponding theoretical simulation is performed for the recording and reconstruction of the lenseless Fourier transform hologram.
