Publication number: 20190250388Abstract: In a first invention, a SCAPE system routes light from a tilted intermediate image plane (170) to an infinity space disposed behind a third objective (180). A first dichroic beam splitter (52) positioned in the infinity space routes light from the intermediate image plane with different wavelengths in different directions. First and second light detector arrays (90) capture first and second wavelength images, respectively, and optical components (54,56,58,82) route light having the first and second wavelengths towards the first and second light detectors, respectively. In a second invention, a SCAPE system is used to capture a plurality of images while a sample is perturbed (e.g., vibrated, deformed, pushed, pulled, stretched, or squeezed) in order to visualize the impact of the perturbation on the sample.Type: ApplicationFiled: September 12, 2017Publication date: August 15, 2019Applicant: The Trustees of Columbia University in the City of New YorkInventors: Elizabeth M.C.

Publication number: 20190250390Abstract: A microscope includes illumination optics for fluorescence excitation of point light sources of a sample, detection optics and a camera having a sensor. A density of the point light sources is kept low so as to minimize a crossover of point light sources that are behind or close to one another in each image captured by the camera. A means for subdividing a detection aperture into individual sub-apertures is provided in a beam path of the detection optics such that images generated by the individual sub-apertures on the sensor of the camera depict an object volume from different spatial directions.Type: ApplicationFiled: May 2, 2017Publication date: August 15, 2019Inventors: Florian Fahrbach, Frank Sieckmann, Christian Schumann, Oliver Schlicker

Publication number: 20190250391Abstract: Tiling light sheet selective plane illumination microscopy (TLS-SPIM) improves the 3D imaging ability of SPIM by using a real-time optimized tiling light sheet. However, the imaging speed decreases, and size of the raw image data increases proportionally to the number of tiling positions in TLS-SPIM. The decreased imaging speed and the increased raw data size could cause significant problems when TLS-SPIM is used to image large specimens at high spatial resolution. An exemplary aspect solves this problem. Discontinuous light sheets created by scanning coaxial beam arrays synchronized with camera exposures are used for 3D imaging to decrease the number of tiling positions required at each image plane without sacrificing the spatial resolution. One exemplary aspect investigates the performance of the method via numerical simulation and discuss the details thereof.Type: ApplicationFiled: February 12, 2019Publication date: August 15, 2019Inventor: Liang GAO
