Abstract
Disclosed are various embodiments for wide-area quantitative phase microscopy using spatial phase scanning digital holography. A motorized micrometer is scanned across a field-of-view, and a camera captures a frame of the field-of-view. The frame of the field-of-view is phase shifted by a predetermined number of pixels. The phase-shifted frame is included in a plurality of phase-shifted frames, and a complex optical field is generated based at least in part on the plurality of phase-shifted frames. A segment of the complex optical field is extracted and appended to a plurality of segments of the complex optical field. A holographic image is generated based at least in part on the plurality of segments of the complex optical field.
