Figure 2
Distortion correction. (a) The orthogonal grid of pixels for a 2 × 2 mm area of the simulated detector face (black), superimposed over the grid of CCD pixels (red), translated back along the taper to show their equivalent areas on the detector face. (b) 100 flood images with an expected value of 100 X-ray photons per pixel were simulated, with full corrections. This image shows the variance of the pixel values calculated over the image ensemble in the same region of the detector as the image in (a). It is evident that the variance is higher (darker pixels) in regions where the pixel grids on the top panel match well, whereas in regions where they match poorly there is a smoothing effect, leading to lower variance but higher covariance. |
