Patents by Inventor Raghav Kumar Chhetri

Raghav Kumar Chhetri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220236550
    Abstract: A sample is imaged using light-sheet imaging. The light-sheet imaging includes generating light, forming one or more light sheets from the light at one or more positions within the sample along respective illumination directions that are parallel with an illumination axis, and recording images of fluorescence emitted along a detection direction from the sample due to the optical interaction between the one or more light sheets and the sample. One or more properties relating to the light-sheet imaging are measured; the one or more measured properties are analyzed; and one or more operating parameters associated with the light-sheet imaging are adjusted based on the analysis of the one or more measured properties.

  • Patent number: 10539772
    Abstract: A method of imaging a live biological specimen includes generating one or more first light sheets; directing the generated one or more first light sheets along respective paths that are parallel with a first illumination axis such that the one or more first light sheets optically interact with at least a portion of the biological specimen in a first image plane; recording, at each of a plurality of first views, images of fluorescence emitted along a first detection axis; generating one or more second light sheets; directing the generated one or more second light sheets along respective paths that are parallel with a second illumination axis such that the one or more second light sheets optically interact with at least a portion of the biological specimen in a second image plane, and recording, at each of a plurality of second views, images of fluorescence emitted along a second detection axis.
