One-shot phase stepping with a pulsed laser and modulation of polarization: application to speckie interferometry

For applications involving time varying optical phase distributions, fast cameras and/or pulsed lasers have to be used. To apply phase?shifting interferometry techniques (PSI) as well, single shot capture is required. Among others, modulation of polarization and phase grating interferometry is a pos...
