Abstract
A method for designing a wide-angle optical system having at least one freeform optical surface without rotational symmetry to create a custom 2D object-image mapping. The method is based on iteratively adjusting the at least one freeform optical 2D surface shape to have the exact 2D object-image mapping required and then adjusting the optical element surfaces to meet the other required optical specifications. The iterative method is applied until both the desired 2D object-image mapping and the other required optical specifications are reached.
