Cutplane of Airy ring pattern: auto-adaptive-gain operation. Comparison between detector output and theoretical prediction for soft X-rays (250 eV photons diffraction through a circular pinhole). Note that the top of the main peak is no longer limited to the full well of a fixed-gain operation mode, as it was for Fig. 8. Pixels amplified by high gain (red) and medium gain (blue data points) are shown with different colours to show the result of the auto-adaptive-gain modulation. Note that, because of parameter dispersion, each pixel has its own gain transition point, which results on some pixels reducing their gain earlier than others. |
