描述了楔形阳极和条形阳极，这是一种多电极平面读出器，用于确定来自微通道板或充气正比计数器的电荷云质心的一维或二维位置。位置读数分为两组：那些只需要检测一个或两个电极上的电荷，以及那些在几个电极之间沉积的电荷的比例是一个独特的功能的电荷云的位置。楔形和条形阳极属于后一组，需要测量每个电极上收集的电荷。然后使用简单算法计算电荷云质心坐标。
Describes the Wedge and Strip Anode, a multi-electrode, planar readout used to determine the one or two dimensional position of the centroid of a charge cloud from a microchannel plate or gas filled proportional counter. Position readouts are categorised into two groups: those requiring solely the detection of charge on one or two out of many electrodes, and those where the ratio of charge deposited amongst several electrodes is a unique function of the charge cloud position. The wedge and strip anode belongs to the latter group which requires a measurement of the charge collected on each electrode. The charge cloud centroid coordinate is then calculated using a simple algorithm.
