Comparison of detection limit between cameras
The two cameras are installed on the same microscope using identical instrument conditions and have almost matching pixel size. Fourier transforms and radially averaged power spectra of 3 × 3 K cropped images from: (A) DDD (1.38 Å/pixel) and (B) CCD (1.37 Å/pixel). High tension 200 keV, electron dose ∼20e−/Å2, exposure time 400 ms. (doi:10.1016/j.jsb.2011.09.002)
