  • Patent number: 11092511
    Abstract: Provided is a device for measuring a lens three-dimensional profile based on laser wavenumber scanning, including: a semiconductor laser for emitting coherent light; a beam splitter for dividing the coherent light into two parts; an optical wedge; a CCD camera for capturing an interference image; a computer for processing image information; a laser controller for adjusting an operating temperature and an operating current of the semiconductor laser; and a bilateral telecentric lens. The coherent light is reflected by the optical wedge and then reaches the bilateral telecentric lens through the beam splitter, to form a first reflected light path. The coherent light is reflected by the measured lens, and then reaches the bilateral telecentric lens through the beam splitter, to form a second reflected light path. The first reflected light path and the second reflected light path form an interference image after passing through the bilateral telecentric lens.

  • Patent number: 11092792
    Abstract: A method for examining a sample in light sheet fluorescence microscopy includes generating an illumination light beam using a light source. The illumination light beam is spatially split into at least two partial illumination light beams using a splitter. The partial illumination light beams are guided through an illumination objective shared by the partial illumination light beams. After the partial illumination light beams have passed through the illumination objective, at least one of the partial illumination light beams is deflected using at least one deflector such that the partial illumination light beams interfere with one another in an illumination plane so as to generate an illumination pattern in the illumination plane. An image of a sample region illuminated by the illumination pattern is produced, wherein detection light that emanates from the sample region reaches a position-sensitive detector through a detection objective.

  • Patent number: 11086117
    Abstract: An apparatus for light-sheet-like light illumination of a sample includes a light source configured to generate an illumination beam. A focusing system is configured to focus the illumination beam to form a light-sheet-like illumination light distribution, with which a focal plane of the sample can be illuminated. An imaging optical unit is configured to image the light-sheet-like illumination light distribution into the focal plane. A polarization element, arranged in a position conjugated to the focal plane between the focusing system and the imaging optical unit, is configured to split the illumination beam into two differently polarized sub-beams, which propagate into the imaging optical unit in different propagation directions, whereby the light-sheet-like illumination light distribution can be imaged by the imaging optical unit in the form of two differently polarized light-sheets, which from a same side of the focal plane are superimposed on each other in the focal plane.

  • Patent number: 11067507
    Abstract: A plasmonic sensor with gradient nanostructures and a method of use thereof is provided. The gradient of shapes will induce different spectral responses at different region of the sensor and show different colors. When there is a change in the environment properties of a substance, such as refractive index, gas concentration or ion density changes, the sensor displays different images, e.g., redial intensity displays and radial color displays. An image recognition based method can be used to extract the environment property with high accuracy according to the sensor image.
