Abstract
Fixed-scale speckles are used in existing ghost imaging system, while the current instrument can achieve multi- scale speckles ghost imaging. This paper focuses on the research of compressed sensing ghost imaging system using multi-scale speckles. Through the computer simulation and using the four resolution scales image as the original image, restored images are obtained to analysis on a variety of different scales and different proportion of speckles cases. The results show that the compressed sensing ghost imaging system using multi-scale speckles can get closer to the true value of image. And when the small scale speckles occupy large proportion, the recovered image resolution is not disturbed.
