  • Patent number: 9594026
    Abstract: The present invention relates to an apparatus for measuring concentration of hemoglobin in blood using a photothermal effect, the apparatus including: a reference light source unit for radiating a reference beam; a photothermal light source unit for radiating a photothermal beam from which the photothermal effect is generated; a cuvette unit for accommodating a collected blood sample thereinto and having first and second reflection layers; and a concentration operation unit for calculating the concentration of hemoglobin by using the phase changes of interference signals generated from the incidence of the reference beam radiated from the reference light source unit onto the first and second reflection layers of the cuvette unit as the photothermal beam radiated from the photothermal light source unit is incident onto the cuvette unit and absorbed by hemoglobin to generate the photothermal effect through the emission of heat.

  • Publication number: 20160109352
    Abstract: The present invention relates to a high-throughput label-free cell assay system which scans a lower part of medium made of glass using an object lens and a Galvano mirror and using a broadband laser as a light source, analyzes and visualizes light reflected from the lower part of the medium using a spectrometer, measures interference spectra formed by the light reflected from each interface of the medium using the spectrometer, and measures phase from data that the measured interference spectra were converted by Fourier transform to observe structural change of cells. The system includes a transparent medium on which a sample is put, an object lens located beneath the transparent medium; a Galvano mirror located beneath the object lens; an optical fiber coupler transferring light from the super-continuum light source to the Galvano mirror; and the spectrometer detecting spectrum of the light from the optical fiber coupler.
