  • Systems and methods for imaging a sample
    Patent number: 11635610
    Abstract: A method for imaging a sample, wherein the sample changes a polarization state of light as a function of position, wherein the method includes changing a polarization state of a purely polarized light of an incident light striking a micro-retarder array, thereby inducing a changed polarization state of the polarization state. The micro-retarder array is placed in a rear conjugate focal plane of a microscope. The method additionally includes projecting the changed polarization state of the polarization state into an object plane of the microscope containing the sample.
    Type: Grant
    Filed: May 18, 2021
    Date of Patent: April 25, 2023
    Assignee: Purdue Research Foundation
    Inventors: Garth Jason Simpson, James Ulcickas, Fengyuan Deng, Changqin Ding

    Publication number: 20200192074
    Abstract: A method for imaging a sample, wherein the sample changes a polarization state of light as a function of position, wherein the method includes changing a polarization state of a purely polarized light of an incident light striking a miro-retarder array, thereby inducing a changed polarization state of the polarization state. The micro-retarder array is placed in a rear conjugate focal plane of a microscope. The method additionally includes projecting the changed polarization state of the polarization state into an object plane of the microscope containing the sample.
