智能x射线光学项目是由英国的六个机构组成的联盟，研究大规模和小规模应用的主动/自适应x射线光学。大规模应用的目标是未来用于x射线天文学的高角分辨率、大型x射线望远镜。本文的工作包括建模和大型样机的测试。该原型将压电装置集成到标准的x射线外壳中，使表面能够主动变形，旨在实现比目前可用的（例如钱德拉0.5英寸）更好的角度分辨率。最初的设计是基于一个薄镍椭球段，在其背面粘接了一系列压电驱动器。介绍了该原型在莱斯特大学x射线束流线上的初步测试结果，并对x射线性能进行了模拟，讨论了驱动压电器件对检测图像的影响以及进一步的模型。
The Smart X-ray Optics project is a UK based consortium of six institutions investigating active/adaptive X-ray optics for both large and small scale applications. The large scale application is aimed towards future high angular resolution, large X-ray telescopes for X-ray astronomy. The work presented here includes the modelling and the testing of the large scale prototype optic. The prototype incorporates piezoelectric devices to a standard X-ray shell to enable the surface to be actively deformed, aiming to achieve an angular resolution better than that currently available (e.g. Chandra 0.5"). The initial design is based on a thin nickel ellipsoid segment on the back of which a series of piezoelectric actuators have been bonded. Results from the initial testing of this prototype in the X-ray beam line at the University of Leicester are presented and simulation of the X-ray performance, the effect of the actuated piezoelectric devices on the detected image and further models are discussed.
