	~~Teng_Mann~~ techniques allows real-time optimization of processing conditions because you can evaluate r<sub>33</sub> during the poling process. It is used to confirm that a sample has been poled. The R33 measurement is best used as a relative measure because it can be inaccurate. Use attenuated total reflection ATR to get an accurate absolute measure.
