  • Publication number: 20230221541
    Abstract: Methods and systems are provided for improving resolution, acquisition speed, and/or illumination dose for microscopy systems. In some embodiments, a microscopy system having multiple objective setups may include illumination generators to provide selectively-blanked illumination line scans, objective lenses to introduce the selectively-blanked illumination line scans to a sample and to collect fluorescence emissions from the sample, and detectors to receive the fluorescence emissions from the objective lenses. The microscopy system may also include one or more processors in operative communication with the detectors, which may combine the fluorescence emissions to generate a composite image.

  • Patent number: 11041807
    Abstract: Various embodiments of a multi-photon microscopy system that uses sequential excitation of a sample through three or more objective lenses oriented at different axes intersecting the sample are disclosed. Each objective lens is capable of focused sequential excitation of the sample that elicits fluorescence emissions from the excited sample, which is then simultaneously detected by each respective objective lens along a respective longitudinal axis every time the sample is illuminated through only a single objective lens.

  • Patent number: 10401604
    Abstract: Embodiments of a resolution enhancement technique for a light sheet microscopy system having a three objective lens arrangement in which one objective lens illuminates a sample and the second and third objective lenses collect the fluorescence emissions emitted by the sample are disclosed. The second objective lens focuses a first portion of the fluorescence emissions for detection by a second detection component, while the third objective lens focuses a second portion of the fluorescence emissions through a diffractive or refractive optic component for detection by a first detector component. A processor combines the images resulting from the first and second portions of the fluorescence emissions for generating composite images with increased axial and lateral resolution.
