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.

Automated adjustment of light sheet geometry in a microscope

A live biological specimen is imaged by generating a plurality of light sheets; directing the plurality of light sheets along an illumination axis through the biological specimen such that the light sheets spatially and temporally overlap within the biological specimen along an image plane, and optically interact with the biological specimen within the image plane; and recording, at each of a plurality of views, images of the fluorescence emitted along a detection axis from the biological specimen due to the optical interaction between the light sheets and the biological specimen. The temporal overlap is within a time shift that is less than a resolution time that corresponds to a spatial resolution limit of the microscope.

Multiview light-sheet microscopy

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.
