Figure 7
Geometrical distortions typical of CCD detectors with demagnifying fiber-optic input. (a) Image of a gridhole mask showing gross distortion with trapezoid shape. (b) Corrected image of a multi-taper CCD system, showing shear distortion at the taper's edge (detail view). The shear was due to the distortion correction and could be further suppressed by using a grid with finer pitch for distortions calibration.
