Abstract: In some remote sensing, such as meteorology and oceanography, wide swath scanning must be used. Owing to the limitation of the detector size, especially in infrared spectrum, the optical-mechanical scanning mode is necessary. Scanning efficiency is an important parameter of those scanners. The high scanning efficiency is one of the goals followed after by the designer of remote sensor. Two high efficient scanning systems are developed by authors. Those systems can have some advantages, such as simple and reliable.

Abstract: In this paper, based on the equations of coupled thermo-elasticity, two-scale asymptotic expressions of the temperature and displacement of composite materials under coupled thermo-elasticity condition are set up with the perturbation method. By the multi-scale finite element method, the temperature and 2-order displacement, strain and stress of composite materials with small periodic configuration under coupled thermo-elasticity condition are calculated. Comparing with the results calculated by finite element method with refined meshes, it’s shown that multi-scale method is an efficient method, and the calculation precision is satisfied.
