Patent number: 11422503Abstract: A method for lens-free imaging of a sample or objects within the sample uses multi-height iterative phase retrieval and rotational field transformations to perform wide FOV imaging of pathology samples with clinically comparable image quality to a benchtop lens-based microscope.

The holographically reconstructed image can be digitally focused at any depth within the object FOV (after image capture) without the need for any focus adjustment, and is also digitally corrected for artifacts arising from uncontrolled tilting and height variations between the sample and sensor planes. In an alternative embodiment, a synthetic aperture approach is used with multi-angle iterative phase retrieval to perform wide FOV imaging of pathology samples and increase the effective numerical aperture of the image.Type: GrantFiled: November 19, 2020Date of Patent: August 23, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Aydogan Ozcan, Alon Grinbaum, Yibo Zhang, Alborz Feizi, Wei Luo
