Development and Improvement of the O-E Payload for UAV

The main function of optoelectronic payload is remote sensing and measuring by optoelectronic sensor in order to search and detect the interested target and locate it with a determinate precision,which implements remote sensing and measuring integrity.One optoelectronic payload for Unmanned Aerial Vehicle (UAV) is made up of 20× optical zoom visible-light TV,wide/narrow Field of View (FOV) movable long wave Forward Looking Infrared (FLIR) and 5Hz repetition frequency laser range finder.They are fixed compactly on a two-axis four-frame stable platform whose stability precision is 25μrad.Based on this configuration,the three axes alignment accuracy of visibility,IR and laser is up to 20″,and the measuring angle precision error is less than 1mrad.The flight-testing indicates that the optoelectronic payload download image is clear and the target orientation data is reliable.Increasing laser repetition frequency and platform isolation can improve the efficiency and quality of searching and detecting.
