Based on curvilinear trajectory equations,the geometrical aberrations and their coefficients with second order approximation have been discussed,and the computational form also given in the paper.

The polarization change of linear polarized light passing through the coaxial lens isanalyzed and the geometric aberration of the lens is also explained.

The transition between geometrical optics and wave optics;

On the basis of theories of physics, geometrical optics and photometry, the optical properties of collimated light beam incident upon single fiber perpendicular to the fiber axis are studied.

In the Cartesian coordinate system,compute the image plane revolution vector quantity caused by scan mirror′s rotation applying coordinate conversion and geometrical optics.

The hybrid analysis of radome based on curvature aperture-integration/geometry optics;

Blur identification is a very important step in the process of constructing high resolution images from low resolution sequence,and it affects the result of practical applications,Based on geometry optics,this paper proposes a novel method to estimate the blur parameters of every frame from three defocused images.
