Abstract

A holographic spatial filtering technique for measuring atmospheric turbulence (C sup 2 (n)), wind speed, and wind direction developed for the NOAA wind profiler II is presented. The technique is based on a device that incorporates a laser array and a holographic filter (the transmitter), a holographic filter, and a detector array (the receiver). The 20cm x 20cm four-channel holographic zero mean filter is being tested in the HOLODAR system which provides simplicity of design, reduced signal/data processing requirements, and improved atmospheric measurement capability. The device can be used for improvements in radars, optical communications, imaging, coherent laser radar, and windshear/vortex detection.
