Photonic spin Hall effect (SHE) holds great potential applications inprecision metrology. How to obtain a high measurement precision is an importantissue to detect the photonic SHE. In this letter, we propose using optimalpreselection and postselection in weak measurements to enhance the measurementprecision. We find that the maximum weak value and pointer shift can beobtained with an optimal overlap of preselection and postselection states.These findings offer the possibility for improving the precision of weakmeasurements and thereby have possible applications for accuratelycharacterizing the parameters of nanostructures.
