    • Centroid locating sensors and methods for locating an illuminated spot on a detector are provided. One sensor includes a plurality of photo-diode (PD) detector elements connected to the PD detector elements. The sensor also includes a plurality of digitization comparators connected to the plurality of PD detector elements and configured to receive output signals from the plurality of PD detector elements and generate a binary 1 output when the output from the PD detector element exceeds a threshold set point and generate a binary 0 output when the output is below the threshold set point. The sensor further includes a plurality of spatial filtering logic circuits connected to the digitization comparators and are configured to receive outputs from a plurality of the PD detector elements and to reject noise for one of the PD detector elements.
    • 提供了用于定位检测器上的照明点的质心定位传感器和方法。 一个传感器包括连接到PD检测器元件的多个光电二极管(PD)检测器元件。 传感器还包括连接到多个PD检测器元件的多个数字化比较器,并被配置为当来自PD检测器元件的输出超过阈值设定点时,从多个PD检测器元件接收输出信号并产生二进制1输出, 当输出低于阈值设定点时,生成二进制0输出。 传感器还包括连接到数字化比较器的多个空间滤波逻辑电路,并且被配置为从多个PD检测器元件接收输出并拒绝PD检测器元件之一的噪声。
