Publication number: 20220317433Abstract: A microscope directs light through an excitation objective to generate a lattice light sheet (LLS) within a sample. A detection objective collects signal light from the sample in response to the LLS and images the collected light onto a detector. Second and third light beams are imaged onto focal planes of the excitation objective and detection objective, respectively. One or more wavefront detectors determine wavefronts of light emitted from the sample and through the excitation objective in response to the imaged second light beam and emitted from the sample through the detection objective in response to the imaged third light beam. A wavefront of the first light beam is modified to reduce a sample-induced aberration of the LLS within the sample, and a wavefront of the signal light emitted from the sample is modified to reduce a sample-induced aberration of the signal light at the detector.Type: ApplicationFiled: December 16, 2021Publication date: October 6, 2022Inventors: Robert Eric Betzig, Tsung-Li Liu, Daniel E.

Publication number: 20220091038Abstract: Imaging a sample that includes phototransformable optical labels (“PTOLs”) with an optical system having a diffraction-limited resolution volume (DLRV), includes providing activation radiation to the PTOLs to activate a statistical subset of the PTOLs. A density of the PTOLs of the activated subset is less than an inverse of the DLRV. Excitation radiation is provided to the activated subset to excite activated PTOLs. Radiation emitted from the activated and excited PTOLs located at different focal planes of the optical system within the sample is detected with the optical system. The preceding steps are repeated one or more times, each time activating a different statistical subset of the plurality of PTOLs. Three-dimensional locations within the sample are determined, with a sub-diffraction-limited accuracy, of the activated and excited PTOLs based on the radiation emitted from the activated and excited PTOLs that is detected from the different focal planes of the optical system.Type: ApplicationFiled: May 13, 2021Publication date: March 24, 2022Inventors: Robert Eric Betzig, Harald F.

Patent number: 10795144Abstract: A sample is bathed in a solution that includes labels having a binding affinity for a structure on the sample and that emit light in response to excitation light. A sheet of excitation light having a FWHM thickness is provided to the sample. Light emitted from labels in response to the excitation light is imaged onto a detector, where the light is imaged with a detection objective having a depth of focus comparable to or greater than the FWHM thickness. The bathing of the sample and the imaging of the light emitted from the bound labels is controlled, such that the imaged light from different individual labels bound to the structure is resolved on the detector. The providing, imaging, and controlling are repeated to image, at different times, light from labels bound to the structure at different locations on or within the sample.Type: GrantFiled: December 7, 2015Date of Patent: October 6, 2020Assignee: Howard Hughes Medical InstituteInventors: Robert Eric Betzig, Wesley Legant

Patent number: 8629413Abstract: A method of manipulating a focused light beam includes focusing a beam of excitation light with a lens to a focal spot within a sample, where a cross-section of the beam includes individual beamlets. Directions and/or relative phases of the individual beamlets of the excitation beam at a rear pupil of the lens are individually varied with a wavefront modulating element, and emission light emitted from the focal spot is detected while the directions or relative phases of individual beamlets are varied.
