Title: Alborz Feizi: Innovator in Lens-Free Microscopy
Introduction
Alborz Feizi is a prominent inventor based in Walnut Creek, CA (US). He has made significant contributions to the field of lens-free microscopy, holding a total of 3 patents. His work focuses on innovative methods for imaging and analyzing biological samples, particularly in the context of yeast cell viability.
Latest Patents
One of his latest patents is titled "Device and method for iterative phase recovery based on pixel super-resolved on-chip holography." This invention describes a method for lens-free imaging of samples, utilizing multi-height iterative phase retrieval and rotational field transformations. The approach allows for wide field-of-view imaging of pathology samples, achieving image quality comparable to traditional lens-based microscopes. The method employs the solution of the transport-of-intensity equation as an initial guess to expedite the image recovery process. Additionally, the holographically reconstructed image can be digitally focused at any depth within the object field of view after image capture, eliminating the need for physical focus adjustments.
Another notable patent is "System and method for determining yeast cell viability and concentration." This invention features a lens-free microscope system designed for the automatic analysis of yeast cell viability in stained samples. The portable device includes a light source coupled to an optical fiber, which is positioned several centimeters away from an image sensor. The stained sample is placed on the image sensor or a nearby sample holder. Hologram images are processed by a computing device equipped with image processing software, which identifies yeast cell candidates and classifies them as live or dead using a trained machine learning model.
