The principle of detection method for ship wake flow based on polarized laser is to efficiently detect and track ship wake flow through detecting scale bubble wake flow and its polarization difference after seawater medium scattering.On basis of analyzing ship wake flow geometric model and the distribution law of bubbles

build ship wake flow polarized laser detection model

a method for ship wake flow detection by polarized laser is proposed

and analyze long distance and short distance wake flow allo-information use polarized light characters

experimental research on feasibility of this method is carried out.Experimental results show that the method is feasible and it is suitable for both long distance and short distance ship wake flow

especially for long diatance ship wake flow detection.
