  • Fiber optic direct-sensing bioprobe using a phase-tracking approach
    Patent number: 5804453
    Abstract: A fiber optic bioprobe in which an immobilized biolayer, such as an antigen or antibody, acts as a sensing etalon of a Fabry-Perot interferometer. The bioprobe is used in a system in which a shift in the spectral dispersion pattern, caused by reflected out-of-phase beams, is used to determine a concentration of a substance in a sample solution.
