  • Publication number: 20250164771
    Abstract: The present invention provides a microscopy imaging system with high spatial and temporal resolution and large field of view. One embodiment provides a combination of large field-of-view (8 mm) with high numerical aperture (0.47), superior temporal resolution (up to 1000 Hz) while maintaining high spatial resolution (i.e., less than 6 ?m), dual-channel synchronized imaging capability, enhanced light collection efficiency (˜85% transmission), and LED synchronization with rolling shutter mechanism of the sCMOS cameras.

  • Publication number: 20250064309
    Abstract: A method for concurrently measuring multiple biological parameters in an animal includes: a) illuminating using multiple illumination sources a region-of-interest of the animal that expresses a first genetically encoded fluorescent indicators (GEFI), a second GEFI, and a long-Stokes-shift (LSS) fluorescent compound that is insensitive to the multiple biological parameters; b) concurrently detecting fluorescence signals from the first GEFI, the second GEFI, and the LSS fluorescent compound using a multi-channel fluorescence sensing optical system; and c) processing the detected fluorescence signals to determine values of the multiple biological parameters, wherein the processing reduces instrument and/or biological artifacts in the values of the multiple biological parameters.

  • Publication number: 20250067672
    Abstract: We combine linear and nonlinear microscopy modalities. This approach is capable of imaging a sample using the two modalities concurrently, generating time sequences of images of the sample having different properties characteristic of each of the modalities. We can separate light emitted from the sample, generated by either modality, even if the spectrum of light is identical for each modality. The nonlinear microscopy modality allows one to create high resolution volumetric images of the sample. The concurrent imaging of the sample using linear and nonlinear microscopy modalities enables one to correlate a spatial structure and temporal dynamics of the sample acquired in each modality allowing one to create a mapping between images across the modalities. The created mapping can be used to match images of a tissue sample acquired using linear modality in a living organism with high resolution, two- or three-dimensional images obtained using nonlinear microscopy modality.

  • Patent number: 11986267
    Abstract: Systems, methods and devices are implemented for microscope imaging solutions. One embodiment of the present disclosure is directed toward an epifluorescence microscope. The microscope includes an image capture circuit including an array of optical sensor. An optical arrangement is configured to direct excitation light of less than about 1 mW to a target object in a field of view of that is at least 0.5 mm2 and to direct epi-fluorescence emission caused by the excitation light to the array of optical sensors. The optical arrangement and array of optical sensors are each sufficiently close to the target object to provide at least 2.5 ?m resolution for an image of the field of view.

  • Publication number: 20230323342
    Abstract: Provided herein are materials and methods useful for facilitating transgene recombination. The present disclosure relates to, for example, techniques for manipulating recombination frequencies and generating organisms that contain multiple transgenic elements docking at the same locus on a single chromosome. The time consumed by the entire recombination process is proportional to the logarithm of the number of transgenes to be recombined.

  • Publication number: 20200100659
    Abstract: Biological tissue such as skeletal and cardiac muscle can be imaged by using an objective-based probe in the tissue and scanning at a sufficiently fast rate to mitigate motion artifacts due to physiological motion. According to one example embodiment, such a probe is part of a system that is capable of reverse-direction high-resolution imaging without needing to stain or otherwise introduce a foreign element used to generate or otherwise increase the sensed light. The probe can include a light generator for generating light pulses that are directed towards structures located within the thick tissue. The system can additionally include aspects that lessen adverse image-quality degradation. Further, the system can additionally be constructed as a hand-held device.

  • Publication number: 20190133449
    Abstract: Analysis of live beings is facilitated. According to an example embodiment of the present invention, a light-directing arrangement such as an endoscope is mounted to a live being. Optics in the light-directing arrangement are implemented to pass source light (e.g., laser excitation light) into the live being, and to pass light from the live being for detection thereof. The light from the live being may include, for example, photons emitted in response to the laser excitation light (i.e., fluoresced). The detected light is then used to detect a characteristic of the live being.
