  • 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

  • Patent number: 11619581
    Abstract: A system including a first micro-retarder array, wherein the first micro-retarder array is configured to convert a purely polarized light of an incident light into two components. The system additionally includes an optical device, wherein the optical device is configured to collimate the two components to two foci planes. Moreover, the system includes a second micro-retarder array, wherein the second micro-retarder array is configured to combine a set of two components of the incident light, thereby producing a second purely polarized light. Further the system includes a detector, wherein the detector is configured to receive the second purely polarized light.

  • 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.
