Validation of PS-PtychoLM optic-axis orientation measurements. (ah) Birefringence maps of a single MSU crystal at different rotation angles (15°,33°,61°,93°,108°,128°,145°, and 178°, respectively). (i) Optic-axis orientation of the MSU crystal measured through rotation at approximately 15° intervals.
