  • Device for investigating non-linear optical behavior of a layer formed from first and second reactants
    Patent number: 6274085
    Abstract: A method and a device for optically ascertaining the mutual binding of a first and a second reactant are described. Use is made of the fact that a dipolar layer (7) having a non-linear optical behavior is formed upon a reaction between the two reactants. The formation of such a layer is ascertained by illuminating the substance with radiation (8) having one or two frequencies, and by detecting whether radiation (10) from the substance contains a component at a frequency which is twice the frequency, or a mixed term of the frequency of the radiation incident on the substance.
    Type: Grant
    Filed: September 10, 1999
    Date of Patent: August 14, 2001
    Assignee: U.S. Philips Corporation
    Inventors: Robertus W. J. Hollering, Maarten Barmentlo
