| 英文摘要 | The random noise of terbulent atmosphere cause the seruious image quality degradation of video images, the cutoff frequency of result is very low when video images were added to improve the SNR. This phenomenon is very obvious especially in astronomical video imaging. A new point of video speckle image that is neither the maximum value point nor the centroid was found. A new image reconstruction method which based on this point was developed. It is a kind of iterative shift-and-add method (ISA). the initial value of this method can be the result of traditional shift-and-add method or the result, of speckle interferometry (Autocorrelation) and so on. The clean methed is used as the deconvolution method of ISA. The deffraction-limited resolution reconstructed results of series video images through terbulent atmosphere show that this method has a high signal-to-noise ratio and wide dynamic range. At last the equipment that we used to detect and save the dim images is introduced and some high resolution results of video images are given. |
