Abstract
Techniques for performing phase detect operations are described. The techniques include obtaining first measurements with a set of half-shield phase-detect sensors; obtaining second measurements with a set of non-phase detect sensors that are not configured as phase-detect sensor; and determining a phase difference based on the first measurements and the second measurements.
