X射线激光全息的可见光再现

THE RECONSTRUCTION OF X-RAY LASER HOLOGRAM WITH VISIBLE LIGHT

Ｘ射线激光全息是Ｘ射线激光一个非常重要的应用。本文模拟了Ｇａｂｏｒ全息的记录和再现过程，分析了Ｇａｂｏｒ全息和无透镜傅立叶变换全息用可见光再现过程中再现象的放大率、象差等对再现象的影响，提出了减小象差和获得高分辨再现象的方法，认为无透镜傅立叶变换全息是当前Ｘ射线激光全息的重要记录方式。

X-ray laser holography is considered to be an important application of X-ray laser.In this papor,the simulation of the record and reconstruction of Gabor hologram is presented,and the influence of image amplification and aberrations for the reconstruction of Gabor hologram and lenseless fourier transform hologram with visible light is discussed,the method to obtain a high resolution amplified reconstruction image with visible light is proposed.The results show that lenseless fourier transform hologram is very important in X-ray laser holography.
