Structured illumination and image enhancement of three-dimensional and moving objects at a distance via incoherent Fourier ptychography.

ABSTRACT

We experimentally apply incoherent Fourier ptychography to enhance the resolution of recorded images by projecting known, uncorrelated, random patterns at high speed onto 3D moving and distant objects. We find that the resolution enhancement factor can be greater than 2, depending on the projection and camera optics.
