Different approaches of 2D lens arrays as Shack-Hartmann sensors for hard X-rays are compared. For the first time, a combination of Shack-Hartmann sensors for hard X-rays (SHSX) with a super-resolution imaging approach to perform multi-contrast imaging is demonstrated. A diamond lens is employed as a well known test object. The interleaving approach has great potential to overcome the 2D lens array limitation given by the two-photon polymerization lithography. Finally, the radiation damage induced by continuous exposure of an SHSX prototype with a white beam was studied showing a good performance of several hours. The shape modification and influence in the final image quality are presented.

基于2D折射透镜阵列和超分辨率多对比度X射线成像的Shack-Hartmann波前传感器。

比较了用于硬X射线的作为Shack-Hartmann传感器的2D透镜阵列的不同方法。首次展示了用于硬X射线的Shack-Hartmann传感器（SHSX）与超分辨率成像方法的结合，以进行多对比度成像。金刚石透镜被用作众所周知的测试对象。交错方法具有克服由双光子聚合光刻所给定的2D透镜阵列限制的巨大潜力。最后，研究了SHSX原型连续暴露于白光束引起的辐射损伤，显示了几个小时的良好性能。介绍了形状修改和对最终图像质量的影响。
