Effectiveness of optical-radiation focusing by multicycle wavefront-inversion system
Tóm tắt
The effectiveness of a multicycle wavefront-inversion (WFI) algorithm in the problem of laser-radiation focusing in a randomly inhomogeneous medium is evaluated. Both “local” (for a single cycle) and “integral” (for the entire observation period) effectiveness criteria are examined. The dependence of these criteria on the main parameters of an adaptive system with WFI are determined. It is shown, in particular, that the WFI system must be adjusted for local conditions to increase the effectiveness of WFI of a “noisy” signal.
