Figure 8
Detailed view on the photons registered within a single illumination spot indicated by the dashed rectangles in Fig. 6. The colour scale indicates the time of photon arrival in microseconds within the shutter. The time window for a single acquisition frame is 9.68 ms. (a, c) Raw image recorded by the MCP/Timepix detector showing multiple pixels excited at the Timepix readout by most photons. (b, d) The same acquisition frame processed by the developed cluster analysis tool. Only one pixel is assigned to each registered photon. Images (c) and (d) show a 3D representation of the measured data: the horizontal plane is the event position xy, and the vertical axis is the timing of the photon arrival (in microseconds). |
