Abstract:
In the paper theoretical bases are presented, as well as their experimental verification, concerning an idea of a new type acousto-optic light ellipticity modulator, based on light diffraction phenomenon by ultrasonic waves, within the so-called intermediate diffraction regime. The experimental data obtained really good match relevant theoretical predictions, and the device examined enables a continuous light ellipticity variation from 0 up to 1, with low diffraction loses and for low electric voltage applied to ultrasonic transducer.
