Beschreibung
Zusammenfassung:	A magnification adjustable projection system includes an imaging system having a first pair of cylindrical lens plates located within an object or image space. The first pair of cylindrical lens plates includes a first cylindrical lens plate axially movable relative to a second cylindrical lens plate. A second pair of cylindrical lens plates is located within the object or image space in optical alignment with the first pair of cylindrical lens plates. The second pair of cylindrical lens plates includes a third cylindrical lens plate axially movable relative to a fourth cylindrical lens plates. First and second actuators adjusts distances between the first and second cylindrical lens plates and between the third and fourth cylindrical lens plates. The first and second pairs of cylindrical lens plates have first and second cylindrical transverse axes that are approximately 45° relative to each other.
