A wavelet-based approach of aerial blurred image restoration is proposed in this article. Image motion is inevitable in photographing for aerospace camera. Though some Image Motion Compensation(IMC) schemes are applied in aerial imaging system  the ultimate image will be blurred in certain extent for the existence of IMC residual error  while the forward image motion is the key element among all image motions which lead to image blurring. First the course of blurring caused by forward image motion is expressed using wavelet transform  and a multiresolution sparse matrix representation of the degeneration model is obtained according to the wavelet transform. Subsequently a regularizing restoration algorithm is deduced from it  and which can smoothly restraint the processed result efficiently. In the end the proposed approach is tested in MATLAB. The blurred image is restored using above-mentioned wavelet algorithm  conventional contrary filter and Wiener filter algorithm separately. The conclusion that the wavelet-based restoration algorithm is superior to other two approaches is obtained by comparing the restored image's value of mean gradient. The calculating quantity of the wavelet-based blurred image restoration approach isn't large and it has good practicability in the field of image interpretation and aerial survey or drawing.

With reactive low voltage ion plating technique  ITO (indium oxide doped with tin) films were deposited on glass substrates by using ITO pellet with a composition of 90 wt.% In2O3 and 10 wt.% SnO2 without extra heating. The post annealing process was done in vacuum with different annealing temperature at 100  200  300 and 400C for 2 hours  respectively. The effects of vacuum annealing on structural  optical and electrical properties of the ITO film deposited by RLVIP were studied in detail. The results showed that the crystalline of the film was improved with the higher temperature. The increase of the annealing temperature improved the infrared reflectivity from 30% to 80% over 8-14m of the infrared atmosphere window  and a simultaneous variation in the optical transmission of the visible spectral region occurred. In addition  sheet resistance of ITO films had contrary changing trend with the IR reflectance  as well.
