The amplitude-phase distribution transformation when the laser radiation reflect from tetrahedral retroreflectors

Annotations languages:

The mechanism of the amplitude-phase distribution (APD) transformation when the laser radiation reflect from tetrahedral retroreflectors (TRR) that differ from each other by physical properties of reflection borders is investigated. The simulation model of such transformation is developed. Simulation results show that having initial uniform APD on the TRR’s input we get irregular amplitude and phase distributions on it’s output. Considerable distinctions for different components of output radiation polarization are also observed.
