The existing slant step edge methods, greatly influenced by the edge? s sub-pixel positioning precision, the Edge spread Function (ESF) Samples5 quality and fitting models of the ES F curve, do not perform-stability and accuracy. An optimized reconstruction algorithm for Point spread Function (PSF) with better precision is proposed using the Slant St EP Edge. The gradient operator is introduced in Edge line fitting to refine the edge points ' sub-pixel positions for greater Accura Cy. The improved method adopts new techniques of moving window in the ESF de-ioising and resampling method to improve ESF Le ' s quality. Finally, robust PSF reconstruction results are obtained by Gaussian function fitting. Experiments demonstrate that the new algorithm shows the very very performance gain in the precision of step edge line fitting and Also the superiority in accuracy and stability of the PSF reconstruction.

For the Water environment and atmospheric environment monitoring, the remote sensing technology is one of the Important technical means, it not only can carry on the real-time monitoring of the water pollution and air pollution, but Also can provide technical support for the scientific, accurate, reasonable and rapid emergency Ion. In recent years, water pollution and air pollution have become worse and worse, which has seriously affected the people ' s Life and industrial production. Therefore, water environment and atmospheric environment, monitoring work becomes particularly. The remote sensing technology, with the continuous development of spaces and time, has a higher spectral, resolution has provided a powerful guarantee for the water and atmosphere environment. This paper mainly describes the basic knowledge to the remote sensing technology, on which basis, it has expounded the FEA Sibility of remote sensing technology in environmental monitoring, besides, through the analysis of the application of REM OTE Sensing technology in water environment and atmosphere environment, it monitoring has further Ion work of water environment and atmosphere environment.
