Wavefront Control of Wide Aperture Laser Beams for Quantum Key Distribution Problems in Free Space

A wavefront sensor based on the Talbot effect has been created. Efficient algorithms for the digital analysis of talbograms have been found. The possibility of visualizing optical density perturbations along the path of a laser beam is demonstrated, which makes it possible to use a wavefront sensor...

Description
Summary:	A wavefront sensor based on the Talbot effect has been created. Efficient algorithms for the digital analysis of talbograms have been found. The possibility of visualizing optical density perturbations along the path of a laser beam is demonstrated, which makes it possible to use a wavefront sensor based on the Talbot effect to create adaptive laser communication systems in free space.
