Method for measuring air turbulence by means of a system handle and system handle for measuring air turbulence

摘要

METHOD FOR MEASURING AIR TURBULENCE THROUGH A LIDAR SYSTEM AND LIDAR SYSTEM FOR MEASURING AIR TURBULENCE. The present invention relates to a method of measuring coping air turbulence, particularly on board an aircraft during which an expanded laser beam (12} of a predetermined wavelength is emitted to a spatial area and light. Returned scattering of this spatial area is received At a first point in time ti and a second point t2 after the emission of a laser pulse (L), the intensity distribution in the cross-section of the scattered light is measured and the air turbulence in the measurement field defined by the points at time t1 and time t2 is determined by comparing both intensity distributions Images of speckle patterns are recorded with the help of cameras (21, 22). (30) conduct a cross correlation to provide visible turbulence and display it on a monitor (35).
