Hard X-ray focusing telescopes can achieve orders of magnitude improvements in sensitivity compared to the instruments based on coded apertures and collimated detectors that have traditionally been employed in this energy band.
      
This is a very important achievement since high energy astronomical missions based on hard X-ray focusing optics are intended in the near future.
      


In order to realize expectant arbitrary focusing length for X--rays, the Surfaces of MCP are curved into spheres about the same "direction, its radius of curvature depends on the focusing length. Using simple one-dimensional model, the parameters of the focusing properties such as the reflection efficiency can be calculated. The conclusions show that this kind of MCP is similar to x-rays lens. Its applications are rather extensive.

为了实现X射线聚焦所期望的任意聚焦长度,将微通道板两端面沿同一侧凹陷成球面,其曲率半径视聚焦长度而定,相应的圆柱形通道发生微小的变化。利用简单的一维模型,计算出X射线经微通道板后的反射效率等一系列聚焦参数。结果表明,这种微通道板类似于X射线透镜,其应用是相当广泛的。

Because drawbacks such as a diffraction efficiency of only about 10%, zone plates have limited applicability in the visible. However, there is now considerable renewed interest in zone plates due mainly to the realization that in the X rays they may be the most direct route to the theoretical limit of resolution, the diffraction limit. In addition to its background, basic concepts and classifications, X ray zone plates manufacturing techniques, recent development and applications were reviewed briefly in this...
