Selection of a two-dimensional image edge using polarisation-independent acousto-optic diffraction

A method for filtering two-dimensional distributions of light-wave spatial frequencies, based on the use of polarisation-independent acousto-optic (AO) Bragg diffraction, is proposed. This method provides a maximally possible transmission bandwidth of spatial frequencies and a minimum size of the re...

Zusammenfassung:A method for filtering two-dimensional distributions of light-wave spatial frequencies, based on the use of polarisation-independent acousto-optic (AO) Bragg diffraction, is proposed. This method provides a maximally possible transmission bandwidth of spatial frequencies and a minimum size of the resolved AO element. A selection of a two-dimensional edge in the zero Bragg order is demonstrated. The main theoretical conclusions are experimentally confirmed using a paratellurite AO filter.
