Abstract
The unrestricted shape of freeforms has opened the possibility of finding solutions clearly exceeding the performance of their rotationally symmetric counterparts. This applies especially to systems where the specifications (either optical or geometrical) deviate from rotational symmetry. For instance, short throw distance multimedia projectors cannot be placed in front of the center of the projected image without blocking the spectators’ ...
