Modulation transfer function measurement in ICF hydrodynamic instability experiments

In hydrodynamic instability experiments, the X-ray intensity distribution will change after passing through the imaging system. In order to acquire the actual X-ray distribution, the MTF of the imaging system have to be measured accurately. The line spread function(LSF) of the imaging system was given by analyzing the edge image. The fourier transform of the LSF is the MTF of the imaging system. The image reconstruction was completed using Weiner filtering and constrained least square filtering. The boundary of the reconstruction image is clear.
