Abstract
A folded optical system for scanning an object and projecting its image in four modes of operation. In one mode, a stationary object is scanned by moving mirrors and its conjugate image projected at unity magnification onto a moving image surface. In a second mode, conjugate distances are varied to project an image at other than unity magnification. In a third mode, the optical system remains stationary and the object is moved relative to it to enable imaging of objects larger than the scan travel of the optics. In a fourth mode, the optics again remain stationary and an add-reflector is introduced to create a reflection cavity to increase the object conjugate for minified imaging of large moving objects. Mirrors and lens are movable to effect magnification changes.
