The distribution model of wavefront aberrations, which takes on a significant role in the designs and alignments of imaging optical systems without vignetting, is newly presented. This model decomposes the complicated distributions into the characteristic components, which clarifies the alignment criteria. For the actual alignments, only small displacements(More)
Mechanical systems or robots to assist landmine detection are expected to greatly improve quality of humanitarian demining tasks. These new systems could provide: i) safer operation; ii) advanced methods for automatic target recognition and discrimination; iii) consistent performance with less influence of " human-factors " ; iv) better detection(More)

The parametric camera model is newly presented in order to calibrate rotationally nonsymmetric and noncentral cameras. This model assumes cameras designed rotationally symmetric and containing manufacturing errors. For this purpose, the general expression of the principal rays, which are equivalent to the backprojection lines corresponding to the image(More)
