Design of Extended Depth-of-Focus Laser Beams Using Orthogonal Beam Expansions

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, we introduce an alternate novel synth...
