Abstract

Speckle interferometry has beenwidely used in the observational astronomy, especially in binary stars.This paper is the part of a series dedicated to the speckle imaging of binary stars carried out by the research team of Shanghai Astronomical Observatory.The observation experiments were carried out with 1.56-m telescope using a speckle camera,and the high resolution image were reconstructed successfully using speckle interferometry and iterative shiftand- add. In order to speed up the computation speed, we also prepared a reconstruction software based on GPU technology and CUDA programming model, compared with C++ program based on CPU, the speed ratio can reach about 7 times.
