Fig. 7

a An original image of the equally spaced pinhole array of camera #1. b The image of camera #1 with the detector nonlinearity corrected. c The final image of camera #1 with all geometrical nonlinearities corrected. d An original image of the equally spaced pinhole array of camera #2. e The image of camera #2 with the detector nonlinearities corrected. f The final image of camera #2 with all geometrical nonlinearities corrected. The coordinates in (c) and (f) correspond to the FOVs of the cameras. The equivalent number of pixels are 340 and 50 for the FOVs of 68° and 10°, respectively
