  • Methods and apparatus for investigation of volume change dynamics of physiologically active samples
    Patent number: 8520215
    Abstract: A transversal change of the position of a measured sample surface exposed to the influence of visible radiation for example actinic light, is measured interferometrically by a reflecting target, which is in mechanical contact with the measured sample surface, and reflects a measuring beam, generated together with a reference beam by a laser source, and the transversal change of the position of the measured sample surface is detected from the phase difference of harmonic waves in the beam of interfering radiation. The device involves, for example, a special detection connection of photodetectors, a measuring unit and a basic module with a computer, the design of reflecting targets for liquid and solid samples, an optomechanical dimension transmitter and a holder of solid samples.
