Paper Abstract

We present a phase imaging system using a novel non-interferometric approach. We overcome the limitations in spatial resolution, optical efficiency, and dynamic range that are found in Shack-Hartmann sensors. To do so, we sample the wavefront using a digital micromirror device. A single lens forms a time-dependent light distribution on its focal plane, where a position detector is placed. Our approach is lenslet-free and does not use any kind of iterative or unwrap algorithm to recover the phase information. The validity of our approach is demonstrated by performing both aberration sensing and phase imaging of transparent samples.
