  • Method and apparatus for scanning with controlled spherical aberration
    Patent number: 9158953
    Abstract: A reader obtains image data corresponding to an image of optically encoded information that is received via a lens unit that causes controlled spherical aberration blurring that is precisely known. The reader may perform deconvolution processing on the image data to render it decodable. The deconvolution processing may implement a Weiner filter that uses data corresponding to a near-field point spread function of the lens unit. The depth of field of the reader is greater than that of conventional reader in all lighting conditions.
