... properties degrade for objects laying at distinct distances than those considered for the design. Since we know the geometry of the catadioptric system, we can compute the direction of light for each pixel ... well as the position of the focal point. The positions of the foci of the two napes of the hyperbola determine the size of the omnidirectional sensor. The catadiopt...
