Paper Abstract

The effect of mechanical vibrations on the shape characteristics and direction of a laser beam of a particular spectrum of vibration is considered. A detection system designed to collect laser pulses emitted by a pulsed laser diode placed onboard of a jet airplane is simulated experimentally. Results show that the area illuminated by a laser beam can vary quite diversely with the frequency and amplitude of the vibration over the period of detection producing a divergence of the laser beam different from that of a static emitter.
