Figure 2
Schematic view of the sensor highlighting the region close to the central rectangular hole. The sensor and hole geometry are shown for two configurations. Left: the top and bottom CCD are moved up and down into an open hole configuration. Right: the smallest hole configuration is shown. Due to the staggered arrangement of the upper and lower CCD, the upper CCD is overlapping the lower CCD such that the slit is completely closed and a 2.4 mm × 2.4 mm large quadratic hole remains in the center of the sensor plane. |
