利用光线追迹的方法模拟了KBA显微镜成像,确定了光轴的方向并计算了KBA显微镜的几何调制传递函数.根据KBA模拟光路,提出了利用可见光作为模拟KBA-X射线显微镜的光轴在激光原型装置上的瞄准和安装的方法,该方法掠入射角的调节精度为0.25°.利用周期为20 μm的Ni网格在激光原型装置上对KBA显微镜进行了X射线成像实验,用X射线CCD记录图像,获得了较清晰的网格图像.

The KBA microscope imaging is simulated by ray-tracing calculation which can determine the direction of optical axis and obtain geometrical modulation tranfer function(GMTF) of KBA microscope.According to the simulation results, a new method is proposed for the aiming and adjustment of KBA microscope at the laser prototype facility using visible light as the simulated optical axis of KBA microscope. The precision of grazing angle is about 0.25°. Experiment of KBA microscope at the laser prototype facility is implemented using Ni-grids whose period is 20 μm, and clear X-ray image of grids is obtained by CCD camera.
