Phase Conjugate Propagation Study.
Abstract
This study addresses two issues that relate to optical communication systems over a propagation path that includes an ensemble of randomly distributed dynamically moving scattering sites. One issue pertains to the reduction of off axis scattering experienced by a probe beam of light that propagates from a remote sensor to an interrogator over the path. A second issue involves the sensing and quantification of any global motion of the scattering sites in the presence of background, random motion. Through the use of nonlinear optical phase conjugation techniques, a wavefront reversed replica of an incident probe beam can be realized that reduces off axis scattering on its return transit through a medium and, at the same time, senses the presence of global phase shifts due to a net motion of an otherwise randomly moving ensemble of scatterers.
