High-resolution synthetic-aperture digital holography with digital phase and pupil correction

Opt Express. 2011 Jun 20;19(13):12027-38. doi: 10.1364/OE.19.012027.


A 218 mega-pixel synthetic aperture was collected by raster scanning a CCD detector in a digital holography imaging experiment. Frames were mosaicked together using a two-step cross-correlation registration. Phase correction using sharpness metrics were utilized to achieve diffraction-limited resolution.
