Figure 1
Projection and scanning geometry of SR-CL in real space (a) and (b) for θ = 45° and θ = 65°, respectively, where θ is the angle between the rotation axis z and the incoming beam. The dark grey bars illustrate the transmitted beam for one projection angle. (c) and (d) show the Fourier domain sampling corresponding to (a) and (b). The dark grey planes correspond to one projection in the Fourier domain. After 360° rotation of the specimen, they form the light grey parts of the Fourier domain. |
