Super-resolution on GIF Quantum® LS imaging filter

Super-resolution on GIF Quantum® LS imaging filter

Thon rings tests performed using GIF Quantum LS imaging filter (K2 camera mounted at the end of GIF Quantum® filter on a Krios microscope) shows signal at near super-Nyquist frequency under low-dose conditions typical of cryo-electron tomography. Left panel is Fourier transform of amorphous test sample (PtIr). Dashed blue circle indicates physical Nyquist, dashed red circle indicates 0.90 super-resolution Nyquist. Upper right panel is the rotationally averaged intensity. Blue dashed line indicates physical Nyquist.
