Designing large Schmidt cameras using the polynomial expansion may yield a not-perfect spherical aberration correction. We indicate an alternative method to design the corrector, whose integration in a software package is in progress. The shape of the corrector can be determined with a simple recursive method. The incidence point can also be calculated for any ray, as well as the corresponding unitary vector normal to the surface.

Abstract
Designing large Schmidt cameras using the polynomial expansion may yield a not-perfect spherical aberration correction. We indicate an alternative method to design the corrector, whose integration in a software package is in progress. The shape of the corrector can be determined with a simple recursive method. The incidence point can also be calculated for any ray, as well as the corresponding unitary vector normal to the surface.File in questo prodotto:
