Abstract:
1. An apparatus for focusing an image of a target object comprising: imaging circuitry for analyzing an image reflected from a target object that is focused onto an imaging sensor coupled to said imaging circuitry; a fixed imaging lens for focusing the reflected image onto said imaging sensor, the fixed imaging lens having an optical axis in alignment with the imaging sensor; a selectable aperture comprising a plurality of apertures of varying sizes, one of said plurality of apertures being selectively selected for optically enhancing the said fixed imaging lens, wherein the plurality of apertures comprises at least one aperture that has an optical element fixed thereon having an optical axis thereof aligned with a center of the at least one aperture; and an actuator coupled to said selectable aperture for selectively selecting said one of said plurality of apertures by moving the selectable aperture along with the plurality of apertures with translational motion in a direction transverse to optical axis for optically enhancing said fixed imaging lens by limiting amount of spherical aberration of said fixed imaging lens; and wherein said actuator coupled to said selectable aperture such that said one of said plurality of aperture is automatically selected by an algorithm residing within an imaging engine of the imaging circuitry that evaluates the proper size of said one aperture.
