  • Patent number: 10514298
    Abstract: A spectrophotometer is provided, which comprises a receiving part diffusing an incident light, a first broadband filter group, and a detector detecting the light having passed through the first broadband filter group, in order to easily select and detect a plurality of lights having specific wavelengths, wherein the first broadband filter group comprises a first broadband filter arranged to have a first angle with respect to an incident direction of light to enable the incident light to pass through a first wavelength band, a second broadband filter arranged to have a second angle, which is different from the first angle, with respect to an incident direction of light to enable the light having passed through the first broadband filter to pass through a second wavelength band, and a first path compensation means for adjusting a path of the light having passed through the second broadband filter to be identical to a path of the light having passed through the first broadband filter, wherein the first broadband

  • Patent number: 10251584
    Abstract: Correction of a non-invasive blood glucose measurement measured from a video image. Correction includes irradiating white light on the skin, filtering the white light reflected from the skin by a first wavelength filter and a second wavelength filter, obtaining a first signal including a blood glucose signal and a pulse signal based on a video image generated by the white light filtered by the first wavelength filter, obtaining a second signal including a pulse signal based on a video image generated by the white light filtered by the second wavelength filter, obtaining a blood glucose signal by subtracting the second signal from the first signal, and calculating the amount of blood glucose in a subcutaneous blood vessel based on the obtained blood glucose signal. Moreover, fundamental blood glucose signals can be extracted in real time without collecting blood.

  • Patent number: 9459257
    Abstract: The present invention relates to a high-speed screening apparatus for a Raman analysis-based high-speed multiple drug. The screening apparatus according to the present invention may easily detect a Raman signal using a core-cap-shell nanoparticle which amplifies the Raman signal by 1012 times and has high reproducibility through Raman spectroscopy in which materials do not interfere with each other and a spectrum has a sharp peak to detect the Raman signal multiple times. Also, since a CCD camera, not a scanner, may be used as the detector, the screening apparatus may multiply screen the drug at a high speed without movement between molecules within a sample. In addition, since multicolors of 5 colors or more may be coated, the screening apparatus may be usefully used for screening various drugs.

  • Publication number: 20160097887
    Abstract: Provided is a monochromatization device for easily selecting light having a specific wavelength, comprising: a first broadband filter arranged to have a first rotational angle with respect to an incident direction of light to enable a first wavelength band to pass therethrough with respect to the incident light; a second broadband filter arranged to have a second rotational angle with respect to an incident direction of light to enable a second wavelength band to pass therethrough with respect to the light passing through the first broadband filter; and a path compensation unit for adjusting a light path so that the light path passing through the second broadband filter is the same as a path of the light incident to the first broadband filter. Accordingly, the output light efficiency for the incident light is increased and the required specific wavelength can be more easily selected.
