Patent ID: 8866063

Claim:
A lens-free system for imaging objects within a sample comprising: a stationary image sensor and a sample disposed adjacent to the image sensor at a distance z 2 ; an illumination source comprising partially coherent or incoherent light in the visible spectrum configured to scan in at least two-dimensions relative to the image sensor and illuminate the sample at a plurality of different locations, the illumination source being located a distance z 1 from the sample, wherein z 2 <<z 1 and wherein the image sensor acquires a lens-free in-line low resolution hologram image of the objects within the sample at the plurality of different locations of the illumination source; at least one processor configured to reconstruct a single high resolution image of the objects within the sample based on the acquired lens-free in-line low resolution hologram image of the objects within the sample obtained from light originating at the plurality of different locations of the illumination source.
