This publisher's note contains corrections to Opt. Lett.45, 77 (202OPLEDP0146-959210.1364/OL.45.000077.Phase birefringence in optical fibers typically fluctuates over their length due to geometrical imperfections induced from the drawing process or during installation. Currently commercially available fibers exhibit remarkably low birefringence, prompting a high standard for characterization methods. In this work, we detail a method that uses chirped-pulse phase-sensitive optical time-domain reflectometry to directly measure positi
