1. An optical projection system to create projected images having dynamically adapting non-linear resolution curves, the optical projection system comprising:
a. a plurality of optical elements configured to create an optical projected image at one or more image planes, the optical projected image having a total field of view, the plurality of optical elements including at least one movable freeform element;
b. at least one actuator configured to move the at least one movable freeform element between at least a first position and a second position different from the first position;
c. a controller configured to control the at least one actuator,
wherein when the at least one movable freeform element is in the first position, the optical projected image created by the plurality of optical elements has a first resolution curve and when the at least one movable freeform element is in the second position, the optical projected image created by the plurality of optical elements has a second resolution curve, the first resolution curve being different than the second resolution curve.
