Comparison of blurred and sharp images in real and frequency space due to TXM system instability. (a) Blurred real space image caused by system instability in TXM. (b) FFT image of the blurred real space image in the frequency domain. (c) Sharp real space image without noise. (d) FFT image of the sharp real space image in the frequency domain. (e) Horizontal power spectrum comparison of the blurred image (b) and the sharp image (d). The inset shows a magnified view of the region indicated by the solid arrow, highlighting the sharp image's higher-frequency information in the horizontal direction. The dashed arrow indicates that the sharp image contains more high-frequency information compared with the blurred image within the signal range. (f) Vertical power spectrum comparison of the blurred image (b) and the sharp image (d). The inset shows a magnified view of the region indicated by the solid arrow, demonstrating that there is no significant difference between the sharp and blurred images in the vertical direction.
