COMPACT DISTORTED ZOOM LENS FOR SMALL ANGLE OF VIEW

摘要

Providing for optical imaging lenses employing non-linear distortion for image magnification is described herein. By way of example, a five-lens system can perform magnification functions by producing distortion that expands the image in the center of the field of view and compresses the image in the periphery of the field of view. This distortion can be corrected through image processing to yield a rectified image. Further, the five-lens system can be implemented as part of a fixed-focus imaging system, or in conjunction with a variable focus optical magnification imaging system.
