To develop a lift early warning infrared device as a part of land or boat (ship) early warning system the system has the ability to target pre-discovery and instructions invasion. Methods: In support of distant air situation alerts the enemy aircraft missiles and other long-range goals obtain the target type and preliminary judgment of grade deliver the alarm information to the command system. The infrared alarm device detects the target's own infrared radiation passively alarms the incoming targets at low altitude and low altitude remote when radar and other equipment is out of work. Results: The accuracy of entire system reached 20 according the analysis. Conclusions: The device has a full range of complex background with high sensitivity high resolution anti-jamming fast response time and other characteristics.

On the analysis of the original data recorder the stress wave theory is the elastic theory can explain the filter buffer question from the micro-small space made several key problems clear when buffer and damping from this designed a composite structure for vibration reduction distinguished between a cushion theory and application field of stress wave theory which made the dynamic stress of protected component down about one order of magnitude. Optimization with Isight and Ls-dyna the traditional rigid spring-buffer model whose object is to reduce the impact of acceleration that can not accurately describe the elastic force of the part of the actual situation the protected component's dynamic stress down about 69.3% and the data recorder's quality 300g lower finally passed the Marshall Hammer test successfully. 2011 Trans Tech Publications.

According to the actual situation when high quality and high precision are required for the image both beforehand and afterwards compensation should be used. In this paper we use Lucy-Richardson algorithm to compensate image motion of a certain aviation camera as an afterwards compensation. Firstly we analyze the imaging principle of the camera and the reasons that cause image motion. Then we have a brief introduce of the Lucy-Richardson algorithm. At last in order to show the feasibility of the method we do some simulation. Through theoretical and practical analysis experiments and test we conclude the Lucy-Richardson algorithm can be used to compensate image motion for the certain camera. 2011 IEEE.

In order to realize autostereoscopic 3D projecting display with higher brightness and larger size a technique of autostereoscopic 3D projecting using parallax barriers and lenticular sheets is proposed.The parameter design of lenticular sheets and parallax barriers is investigated.First projection distance of projector array is confirmed according to eye's resolution then the strips' character of lenticular sheets is analysed by zemax in four-view situation thickness and parameters of strips of lenticular sheets are confirmed. Finally the width of slit and pitch and viewing distance and etc of parallax barriers are confirmed according to parameters of strips of lenticular sheets.Data analysis indicate that the brightness of our four-view image is increased three times because of using lenticular sheets instead of parallax barriers comparing with the autostereoscopic 3D projector using two parallax barriers plates.Parameters design of parallax barriers and lenticular sheets are finished the feasibility and advantages of the 3D display of projecting are confirmed theoretically. 2011 IEEE.
