Information × Registration Number 0207U008210, 0107U000831 , R & D reports Title Design of physical value sensors on the base of integral and waveguide optics popup.stage_title Head Cherpak Vladyslav, Registration Date 29-11-2007 Organization Lviv Polytechnic National University popup.description2 The structure of fibre-optic optic sensor, in which as sensitive element was used the thin polyaniline films formed on optical fibre core with removed cladding by chemical polymerization and vacuum deposition methods was developed. As processing wavelength was suggested to choose 570 nm and 900 nm, due to maximum optical absorption changing on polyaniline films. The suggested fibre-optical sensor of pH value and ammonia didn't request additional liberalization of output signal on pH value range 3-10 and ammonia pressure 20-80 kPa, because of films optical response in 570 nm and 900 nm wavelength ranges are linear.
