Peak-height extraction-process simulation results of JWST-like segmented imaging system. Samples of (a1)–(f1) aberrated PSFs and (a2)–(f2) modulated PSFs captured during scanning. (a3)–(f3) Differential MTFs calculated by Fourier transformer and differential operation. (a4)–(f4) Extracted peak heights that characterise the pistons of all non-reference segments.
