研究了一种用于微通道板传感器的新型光子计数成像读出器——交叉带阳极。利用两层正交感测带集合上检测到的信号的电荷质心来推导光子位置。XS阳极的空间分辨率（< 3 μm FWHM）超过了大多数直接电荷传感阳极的空间分辨率，并且是在低增益（< 2 x 10(6)）下实现的。图像的线性度和保真度足够高，可以分辨和绘制7万个MCP孔，为天文学和其他应用提供了新的可能性。(C) 2003 Elsevier Science B.V.版权所有
A new photon counting, imaging readout for microchannel plate sensors, the cross strip (XS) anode, has, been investigated. Charge centroiding of signals detected on two orthogonal layers of sense strip sets are used to derive photon locations. The XS anode spatial resolution (< 3 μm FWHM) exceeds the spatial resolution of most direct charge sensing anodes, and does so at low gain (< 2 x 10(6)). The image linearity and fidelity are high enough to resolve and map 7 mum MCP pores, offering new possibilities for astronomical and other applications. (C) 2003 Elsevier Science B.V.
