Speckle images are produced by the reflected and scattered light beams from rough surface through free-space to observing plane when laser illuminates the object surface.

On the base of heat transfer theory and glass tempering furnace industrial application,the two practical mathematic models of plane and roll are established,and the image simulation of calcution result is done.

SAR(Synthetic Aperture Radar) image simulation has been widely applied in designing and testifying SAR system,SAR image ortho-correction,Radar image interpretation and target recognition and so on.

This paper firstly introduces the importance of SAR image simulation,then not only decribes their principium and characteristics in detail,but also gives their flow chart separately.

Application of a digital speckle image correlation technique to vibration displacement measurement of an offshore platform model;

The basic principle of speckle image correlation digital technique was introduced firstly in this paper.

The concrete cavity block building is effected mainly by the temperature crack,so a speckle image correlation digital technique is introduced to monitor the temperature crack of concrete cavity block building,and the temperature crack distortion curve of the building is obtained.
