Abstract

The present invention provides a small and fast zoom system using micromirror array lens (MMAL). Thanks to the fast response and compactness of the MMAL as well as absence of the macroscopic mechanical movements of lenses, the zoom system of the present invention fastens the speed of the zooming and reduces the space and weight for the zoom system. Also the present invention provides magnifying the area not on the optical axis and can compensate the aberration of the zoom system.
