Abstract
A device with an acousto-optic polarization splitter as the basic unit has been developed to record polarization-modulated optical signals. It spatially separates input radiation into two beams with mutually orthogonal polarizations. The difference of their intensities serves as the measure of changes in the input-radiation polarization plane. Experiments were performed using a TeO2 single crystal as the acousto-optic splitter and showed the high efficiency of splitting optical radiation with a wavelength of 0.63 μm in the range of acoustic frequencies of 10–26 MHz.
