Laser beams with extended depth of focus have many practical applications, such as scanning printed bar codes. Previous work has concentrated on synthesizing such beams by approximating the nondiffracting Bessel beam solution to the wave equation. In

This paper describes the basic design principles for a new series of bar code scanners from Symbol Technologies. Traditional bar code scanners include an edge detector which has several innate limitations. We propose replacing this edge detector with
