  • Patent number: 11327018
    Abstract: An image reconstruction method includes capturing a reference image of the specimen and capturing a set of original images based on the reference image. The method includes generating a set of analyzed images based on the set of original images by determining an intensity distribution for each pixel of each original image of the set of original images and combining the intensity distribution at each pixel location across the set of original images into an intermediate image. The method includes, identifying an object in the intermediate image. In response to identifying the object in the intermediate image, determining an intensity value of the object in each original image of the set of original images and generating an improved image of the object based on the determined intensity value of the object. The method includes generating a final image including the improved image of the object and displaying the final image.

  • Patent number: 11237109
    Abstract: The present disclosure relates to spatially modulating the light source used in microscopy. In some cases, a light source projects a sequence of two-dimensional spatial patterns onto a sample using a spatial light modulator. In some cases, the spatial patterns are based on Hadamard matrices. In some cases, an imaging device captures frames of image data in response to light emitted by the sample and orthogonal components of the image data are analyzed by cross-correlating the image data with the spatial pattern associated with each frame. A microscope may be calibrated by illuminating a sample with the sequence of spatial patterns, capturing image data, and storing calibration that maps each pixel of the spatial light modulator to at least one pixel of the imaging device.

  • Publication number: 20140103231
    Abstract: The system for detecting volatile organic compounds (VOCs) of this present invention comprises a detecting material made by blending a nano-material and a conductive polymer. The system for detecting VOCs presents the property of high sensitivity, high sensing accuracy, quick response, and real-time VOC detecting, and is demonstrated in the present work for commercialization usage. The system for detecting VOCs can be easily operated to detect VOC without electronic detecting method, and hence this invention can reduce a lot of operation energy and procedure. Furthermore, when adding inorganic nanoparticles, the area of VOC exposure of this invention is increased and the molecular morphology variation of the detecting material is enhanced, and hence the detecting activity of the system for detecting VOCs is improved.

  • Publication number: 20140097358
    Abstract: In a method for imaging a structure (33) marked with a fluorescent dye in a sample, the sample is repeatedly scanned in a scanning range (28) with a light intensity distribution localised around a focal point (29) of a focused fluorescence excitation light beam. The light intensity distribution further comprises a focused fluorescence inhibiting light beam (7) whose wave fronts are modulated so that a fluorescence inhibiting light intensity distribution comprises a minimum at the focal point (29) of the fluorescence excitation light beam (4). The scanning conditions are coordinated in such a way that the fluorescence light is emitted out of the scanning range (28) as individually detectable photons. When these photons are detected, the location (32) of the focal point (28) at the respective point in time is allocated to them. An image of the structure (33) is composed of the locations (32) to which the detected photons have been allocated during several repetitions of scanning the scanning range (28).
