Abstract
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.
