Laser fibre-optical system with digital registration of a signal for air stream turbulent pulsations measurement

Experimental researches of optical fibre sensor characteristics working by scheme of a light marker with laser radiation modulation with digital camera signal registration are executed. During the work the laboratory model of laser system diagnostics turbulence statistical characteristics is created on the basis of photographic registration of the accumulated bidimentional signals of the fibre-optical sensor. The photographic technique registration of a deflection of a working element of fibre-optical system is developed. Experimental check of results of calculation of resonant frequencies of the sensor is carried out.
