我们描述了半影成像技术在激光内爆靶硬X射线成像中的应用。该技术利用的事实是,空间信息可以恢复从阴影或半影,一个未知的来源通过一个简单的大圆孔。成像系统包括一个大的圆形孔径(半影孔径),过滤器,和一个敏感的X射线CCD相机作为探测器。获得了光子能量为5 keV和10 keV ~ 30 keV的X射线图像。我们还提出了一种新的重建方法的半影图像的功率倒谱的基础上,它不需要关于孔径函数的确切信息。
We describe the use of penumbral imaging technique for hard X-ray imaging of laser-imploded targets. The technique uses the facts that spatial information can be recovered from the shadow or penumbra that an unknown source casts through a simple large circular aperture. The imaging system consists of a large circular aperture (penumbral aperture), filters, and a sensitive X-ray CCD camera as a detector. The X-ray images with photon energies of 5 keV and 10 keV to 30 keV have been obtained. We also propose a new reconstruction method based on power cepstrum of the penumbral image, which does not require exact information about the aperture function.
