Abstract


Estimations of temporal and spatial noises and signal-to-noise ratios for image registration method of single exposure with spatial averaging were performed. Two necessary conditions for achievement of the maximum increase of signal-to-noise ratio were defined. The obtained experimental results confirm theoretical estimations of changing spatial resolution and achievable increase of signal-to-noise ratio in registered images. Joint usage for increase of signal-to-noise ratio of the considered method of single exposure with spatial averaging and the method of multiple exposure will allow to flexibly combine requirements to the speed of image registration and to the quantity of resolvable elements in image.
