  • Patent number: 11150461
    Abstract: The present invention discloses a system and a method for phase contrast microscopy imaging. The system includes a microscope, a light source array, an image acquisition module and a calculation module. The light source array includes a fixture having a through hole and two light source groups arranged around the through hole. The two light source groups emit a first beam and a second beam symmetrically arranged about a optical axis of the microscope to illuminate a specimen. The light beams enter and get scattered in the specimen and are obliquely transmitted through the specimen, and collected by the microscope after passing through the through hole. The image acquisition module acquires a first image corresponding to the first beam and a second image corresponding to the second beam. The calculation module obtains a phase contrast image according to the first and second image.

  • Publication number: 20210282661
    Abstract: The present invention discloses a method and system for determining orientation of a capsule endoscope. An external magnetic field is provided outside the capsule endoscope, and an internal magnetic field is provided inside the capsule endoscope. Magnetic field data is obtained according to the external magnetic field and the internal magnetic field, and acceleration data of the capsule endoscope is obtained. When the polarization direction of the external magnetic field is horizontal, the orientation information of the capsule endoscope is obtained according to the acceleration data. When the polarization direction of the external magnetic field is non-horizontal, the orientation information of the capsule endoscope is obtained according to the acceleration data and the magnetic field data.

  • Publication number: 20210167084
    Abstract: A method for forming a three-dimensional (3D) memory device includes forming a cut structure in a stack structure. The stack structure includes interleaved a plurality of initial sacrificial layers and a plurality of initial insulating layers. The method also includes removing portions of the stack structure adjacent to the cut structure to form a slit structure and an initial support structure. The initial support structure divides the slit structure into a plurality of slit openings. The method further includes forming a plurality of conductor portions in the initial support structure through the plurality of slit openings. The method also includes forming a source contact in each of the plurality of slit openings. The method also includes removing portions of the initial support structure to form a support structure. The support structure includes an adhesion portion extending through the support structure.
