Piston Error Evaluation and Correction for Multi-aperture Imaging System
Journal of Physics: Conference Series, 2021 Abstract In this paper, the imaging quality of a three-aperture Golay3 imaging system is studied. The formula of point spread function (PSF) is derived when piston errors exist among each subaperture. The 1951 resolution target is used to analyze the imaging quality under the influence of different piston errors.
