Abstract :
Summary from only given. The experimental setup adopted to characterize subsonic air jets and scattering rotating wheels using photo-EMF sensors and pulsed laser sources is presented. The Q-switched, frequency-doubled Nd:YAG laser had the pulse width of 10 ns and 10 Hz repetition rate. Neutral density (ND) filters were used to attenuate the laser power to avoid saturating the detection electronic circuit.
