  • Patent number: 11317836
    Abstract: The present invention relates to non-invasive blood glucose measuring apparatus and method. More specifically, the apparatus is inserted into a blood vessel of a human body, and at a point of time when a measurement is desired, wirelessly transmits power so as to be operated, wherein a dipole antenna-form sensor measures a change in a specific parameter depending on a blood glucose level. The apparatus measures the blood glucose in a non-invasive manner, wherein a display unit that is present outside the human body receives the parameter value through wireless communication and displays a corresponding blood glucose level.

  • Publication number: 20180073979
    Abstract: Provided are a defect inspection system and a method of inspecting a defect, by which a defect in an inspection target may be precisely detected at a high speed. The defect inspection system includes a light source, a linear polarizer to linearly polarize light from the light source, a compensator to circularly or elliptically polarize light from the linear polarizer, a stage on which an inspection target is located, a polarization analyzer to selectively transmit light reflected by the inspection target, and a first camera to collect light from the polarization analyzer. Light transmitted through the compensator is obliquely incident to the inspection target, and reference light, which corresponds to light reflected in a defectless state, from among the light reflected by the inspection target, is blocked by the polarization analyzer.
