Aperture controlled laser beam shaping techniques for scanning optical code

Invention: Aperture controlled laser beam shaping techniques for scanning optical code

Year	Description
2001	Invention patented by Vladimir Gurevich, Mark Krichever, and Yajun Li on August 1st, 2001. Abstract: An improved optical system for scanning optical codes is disclosed. A laser beam produced thereby is a diverging, nearly diffraction free beam and may be used to produce an elongated scanning spot. An aperture may be employed such that variation in size of the aperture in one orthogonal dimension varies the size of the scanning spot in another orthogonal dimension.
