A gas sensor based on spontaneous Raman scattering is proposed for the compositional analysis of single breath events and for an anesthesia simulation under clinical relevant conditions. A description of the sensor as well as a comprehensive characterization of the system is carried out in order to determine the measurement uncertainty. Finally, the sensor is applied to consecutive breath events and...
The article presents four branches of multi-year research of human breathing. They are (1) modeling and study the movement of the convective flows in the artificial models of nose; (2) numerical modeling of the convective flows movement on the computer models; (3) breathing research with the help of diagnostic equipment; (4) determination of the exhaled air composition. In all our studies the breathing...
We present a method for heat flux measuring with the use of polarization properties of ferroelectric ceramics. Heat flux innovative sensor is developed on the basis of the proposed method. Its experimental verification is carried out. The measurements are based on maintaining a balance between the processes caused by thermal energy and the energy of the electric field in the ferroelectric ceramics...
We introduce a novel strategy to acquire gas phase temperatures by O2 pure rotational CARS during flame spray pyrolysis (FSP) for silica production. RCARS benefits from a polarization filtering technique that is essential in particle and droplet environments. Particle containing regions were located by correlating laser-induced breakdown (LIB) in a particle-laden and a particle-free flame at different...
We utilize laser-induced breakdown spectroscopy for measuring mixture composition and temperature in flames. Spectroscopy of the plasma emission yields concentration information, while temperature is derived from the breakdown threshold pulse energy.
We introduce a novel strategy to acquire CH PLIF images at high repetition rates. A multi-mode pumped optical parametric oscillator (OPO) which produces signal at 431 nm is used for direct excitation of the CH radical.
Time-resolved picosecond pure-rotational coherent anti-Stokes Raman spectroscopy is demonstrated for thermometry and species concentration determination in flames. Time-delaying the probe pulse enables successful suppression of unwanted signals. A theoretical model is under development.
