Abstract
A magnification adjustable projection system is provided that includes an imaging system having an object or image space, a first deformable lens plate located within the object or image space for contributing a first magnification power to the imaging system as a function of an amount of curvature of the first deformable lens plate, and a second deformable lens plate located within the object or image space for contributing a second magnification power to the imaging system as a function of an amount of curvature of the second deformable lens plate. The projection system also has first and second bending apparatuses that adjust the curvature of the first and second deformable lens plate through a range of curvature variation for adjusting the magnification power of the imaging system.
